A digital system^[1] is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete, such as numbers, letters or computer icons, or continuous, such as sounds, images, and other measurements of continuous systems.

The word digital comes from the same source as the word digit and digitus (the Latin word for finger), as fingers are used for discrete counting. It is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography.

[edit] Digital noise

When data is transmitted, or indeed handled at all, a certain amount of noise enters into the signal. Noise can have several causes: data transmitted wirelessly, such as by radio, may be received inaccurately, suffer interference from other wireless sources, or pick up background noise from the rest of the universe. Microphones pick up both the intended signal as well as background noise without discriminating between signal and noise, so when audio is encoded digitally, it typically already includes noise.

Electric pulses transmitted via wires are typically attenuated by the resistance of the wire, and changed by its capacitance or inductance. Temperature variations can increase or reduce these effects. While digital transmissions are also degraded, slight variations do not matter since they are ignored when the signal is received. With an analog signal, variances cannot be distinguished from the signal and so provide a kind of distortion. In a digital signal, similar variances will not matter, as any signal close enough to a particular value will be interpreted as that value. Care must be taken to avoid noise and distortion when connecting digital and analog systems, but more when using analog systems.

[edit] Symbol to digital conversion

Since symbols (for example, alphanumeric characters) are not continuous, representing symbols digitally is rather simpler than conversion of continuous or analog information to digital. Instead of sampling and quantization as in analog-to-digital conversion, such techniques as polling and encoding are used.

A symbol input device usually consists of a number of switches that are polled at regular intervals to see which switches are pressed. Data will be lost if, within a single polling interval, two switches are pressed, or a switch is pressed, released, and pressed again. This polling can be done by a specialized processor in the device to prevent burdening the main CPU. When a new symbol has been entered, the device typically sends an interrupt to alert the CPU to read it.

For devices with only a few switches (such as the buttons on a joystick), the status of each can be encoded as bits (usually 0 for released and 1 for pressed) in a single word. This is useful when combinations of key presses are meaningful, and is sometimes used for passing the status of modifier keys on a keyboard (such as shift and control). But it does not scale to support more keys than the number of bits in a single byte or word.

Devices with many switches (such as a computer keyboard) usually arrange these switches in a scan matrix, with the individual switches on the intersections of x and y lines. When a switch is pressed, it connects the corresponding x and y lines together. Polling (often called scanning in this case) is done by activating each x line in sequence and detecting which y lines then have a signal, thus which keys are pressed. When the keyboard processor detects that a key has changed state, it sends a signal to the CPU indicating the scan code of the key and its new state. The symbol is then encoded, or converted into a number, based on the status of modifier keys and the desired character encoding.

A custom encoding can be used for a specific application with no loss of data. However, using a standard encoding such as ASCII is problematic if a symbol such as 'ß' needs to be converted but is not in the standard.

[edit] Properties of digital information

All digital information possesses common properties that distinguish it from analog communications methods:

• Synchronization: Since digital information is conveyed by the sequence in which symbols are ordered, all digital schemes have some method for determining the beginning of a sequence. In written or spoken human languages synchronization is typically provided by pauses (spaces), capitalization, and punctuation. Machine communications typically use special synchronization sequences.
• Language: All digital communications require a language, which in this context consists of all the information that the sender and receiver of the digital communication must both possess, in advance, in order for the communication to be successful. Languages are generally arbitrary and specify the meaning to be assigned to particular symbol sequences, the allowed range of values, methods to be used for synchronization, etc.
• Errors: Disturbances (noise) in analog communications invariably introduce some, generally small deviation or error between the intended and actual communication. Disturbances in a digital communication do not result in errors unless the disturbance is so large as to result in a symbol being misinterpreted as another symbol or disturb the sequence of symbols. It is therefore generally possible to have an entirely error-free digital communication. Further, techniques such as check codes may be used to detect errors and guarantee error-free communications through redundancy or retransmission. Errors in digital communications can take the form of substitution errors in which a symbol is replaced by another symbol, or insertion/deletion errors in which an extra incorrect symbol is inserted into or deleted from a digital message. Uncorrected errors in digital communications have unpredictable and generally large impact on the information content of the communication.
• Copying: Because of the inevitable presence of noise, making many successive copies of an analog communication is infeasible because each generation increases the noise. Because digital communications are generally error-free, copies of copies can be made indefinitely.
• Granularity: When a continuously variable analog value is represented in digital form there is always a decision as to the number of symbols to be assigned to that value. The number of symbols determines the precision or resolution of the resulting datum. The difference between the actual analog value and the digital representation is known as quantization error. Example: the actual temperature is 23.234456544453 degrees but if only two digits (23) are assigned to this parameter in a particular digital representation (e.g. digital thermometer or table in a printed report) the quantizing error is: 0.234456544453. This property of digital communication is known as granularity.
• Compressible: According to Miller, "Uncompressed digital data is very large, and in its raw form would actually produce a larger signal (therefore be more difficult to transfer) than analog data. However, digital data can be compressed. Compression reduces the amount of bandwidth space needed to send information. Data can be compressed, sent and then decompressed at the site of consumption. This makes it possible to send much more information and result in, for example, digital television signals offering more room on the airwave spectrum for more television channels."^[2]

[edit] Historical digital systems

Even though digital signals are generally associated with the binary electronic digital systems used in modern electronics and computing, digital systems are actually ancient, and need not be binary or electronic.

• Written text in books (due to the limited character set and the use of discrete symbols - the alphabet in most cases)
• An abacus was created sometime between 1000 BC and 500 BC , it later become a form of calculation frequency, nowadays it can be used as a very advanced, yet basic digital calculator that uses beads on rows to represent numbers. Beads only have meaning in discrete up and down states, not in analog in-between states.
• A beacon is perhaps the simplest non-electronic digital signal, with just two states (on and off). In particular, smoke signals are one of the oldest examples of a digital signal, where an analog "carrier" (smoke) is modulated with a blanket to generate a digital signal (puffs) that conveys information.
• Morse code uses six digital states—dot, dash, intra-character gap (between each dot or dash), short gap (between each letter), medium gap (between words), and long gap (between sentences)—to send messages via a variety of potential carriers such as electricity or light, for example using an electrical telegraph or a flashing light.
• The Braille system was the first binary format for character encoding, using a six-bit code rendered as dot patterns.
• Flag semaphore uses rods or flags held in particular positions to send messages to the receiver watching them some distance away.
• International maritime signal flags have distinctive markings that represent letters of the alphabet to allow ships to send messages to each other.
• More recently invented, a modem modulates an analog "carrier" signal (such as sound) to encode binary electrical digital information, as a series of binary digital sound pulses. A slightly earlier, surprisingly reliable version of the same concept was to bundle a sequence of audio digital "signal" and "no signal" information (i.e. "sound" and "silence") on magnetic cassette tape for use with early home computers.

DeAndre Cortez Way (born July 28, 1990), better known by his stage name Soulja Boy Tell 'Em, or simply Soulja Boy, is an American rapper, record producer, actor, and entrepreneur.

In September 2007, his single "Crank That (Soulja Boy)" reached number one on the Billboard Hot 100. The single was initially self-published on the internet, and it later became a number-one hit in the United States for seven non-consecutive weeks starting in September 2007.^[3] On August 17 Way was listed at #18 on the Forbes list of Hip-Hop Cash Kings of 2010 earning $7 million for that year.^[4]

Way has currently released three studio albums and one independent album: his debut studio album Souljaboytellem.com (2007) was certified platinum by the RIAA. However, his next two albums, iSouljaBoyTellem (2008) and The DeAndre Way (2010) did not match the commercial success of his debut, the latter only selling 100,000 copies,^[5] despite the success of several singles across both albums, such as "Kiss Me Thru the Phone" and "Turn My Swag On" (iSouljaBoyTellem) and "Pretty Boy Swag" (The DeAndre Way).

On October 18, 2011, Soulja Boy released his documentary bio pic, Soulja Boy: The Movie.

As of 2011, Way has confirmed he is working on his fourth studio album, entitled Promise, which will be released in April 2012.^[6]

[edit] Early life

DeAndre Way was born in Chicago and moved to Atlanta at age 6,^[7] where he became interested in rap music.^[8]

[edit] Career beginnings

At age 14, he moved to Batesville, Mississippi, with his father, who provided a recording studio for Way to explore his musical ambitions.^[7] In November 2005, Way posted his songs on the website SoundClick. Following positive reviews on the site, he then established his own web pages on YouTube and MySpace.^[9][10] In March 2007, he recorded "Crank That" and released his first independent album Unsigned & Still Major: Da Album Before da Album, followed by a low-budget video filmed demonstrating the "Crank That" dance. By the end of May 2007, "Crank That (Soulja Boy)" received its first airplay and Way met with Mr. Collipark to sign a deal with Interscope Records.

[edit] 2007-08: Souljaboytellem.com

Soulja Boy performing "Crank That (Soulja Boy)" in February 2008.

On August 12, 2007, the song appeared on the Emmy-award winning HBO series Entourage, and by September 1, it topped the Billboard Hot 100 and Hot RingMasters charts.^[11] Way's major label debut album Souljaboytellem.com, which was reportedly recorded using just the demo version of FL Studio,^[8][12] was released in the United States on October 2,^[13] peaking at #4 on both the Billboard 200 and Top R&B/Hip-Hop Albums charts.^[14]

For the 50th Grammy Awards, Way was nominated for a Grammy Award for Best Rap Song with "Crank That (Soulja Boy)". He lost to Kanye West's and T-Pain's "Good Life".

Souljaboytellem.com received a favorable review from Allmusic,^[13] but received mainly negative reviews from other sources such as Entertainment Weekly.^[15] Several reviewers credited Soulja Boy with spearheading a new trend in hip-hop, while speculating he will likely be a one-hit wonder.^[16][17][18]

[edit] 2008-09: iSouljaBoyTellem

The follow-up to souljaboytellem.com, iSouljaBoyTellem, was released on December 16, 2008, to negative critical reception.^[19] The first single from the album, "Bird Walk", peaked at #40 on the Billboard Hot R&B/Hip-Hop Songs chart and the top 20 on the Hot Rap Tracks chart it was performed on the first YouTube Live on November 22, 2008, with an introduction from MC Hammer.^[20] "Kiss Me Thru the Phone", with Sammie, followed, peaking at #3 on the Hot 100 and #1 on the Hot Rap Tracks charts.^[21] Chris Brown was originally Way's first choice to sing the hook, but respectfully turned down the offer. Way then tried to do it on his own with Auto-Tune but he found it unacceptable.^[22] It sold over 2,000,000 digital copies in the United States, becoming his second song to reach the two million mark in downloads.^[23][24]

On January 26, 2009 Way released his third single "Turn My Swag On". it topped the US Rap Charts and peaked at #19 on the Billboard Hot 100. It has so far sold more than 1,000,000 digital downloads in the United States. It became Soulja Boy's third song to sell 1 million or more downloads.^[24]

[edit] 2009-2010: The DeAndre Way

The DeAndre Way^[25] is Way's third studio album, Way has stated that the album is intended to be his most personal and successful album thus far. When speaking on possible collaborations, he stated he wished to work with artists such as Jay-Z, Lil Wayne, and Kanye West,^[26] Eminem,^[27] among others. The lead single from the album, "POW", was released in January 2009 but failed to garner success and was dubbed a promo single. On October 30, 2009 Way released three mixtapes Paranormal Activity, Dat Piff & Cortez.^[28] Then it was announced on February 18, 2010 that the first single from the album was gone be "All Black Everything" but it was cancelled & was just put on his promotional mixtape Legendary.^[29] The album was titled "The DeAndre Way" but was changed in early 2010 to Dre with a commercial video snippet for "Do It Big" as the first single but it was cancelled as well.^[30] However it was reverted back to The DeAndre Way in July 2010.

But on June 8, 2010, the official lead single from the album was "Pretty Boy Swag". The single has reached #34 on the Billboard Hot 100, number six on the Billboard Hot R&B/Hip-Hop Songs chart and number five on the Billboard Rap Songs chart.^[31] The album's second single was due to be "Digital" but it was just used on his promotional mixtape Best Rapper.^[32] Then it was announced that "Speakers Going Hammer" was gone be the second single, but "Blowing Me Kisses" was released on August 31, 2010 as the second single instead.^[33] On October 13 Soulja Boy performed "Pretty Boy Swag" & a snippet of his third single "Speakers Going Hammer". On October 19, 2010 Way finally released "Speakers Going Hammer" on iTunes the single peaked at #48 on the Hot R&B & Hip Hop tracks Billboard.^[34] The DeAndre Way was released on November 30, 2010 it has so far has only sold 70,000 copies making this Way's lowest selling album. Soulja Boy was to be part of the Summerbeatz tour held in Australia alongside Flo Rida, Jay Sean and Travie McCoy in November 2010, but in lieu of his current album release date Soulja Boy had declined the offer & just embarked on his Who They Want tour.

[edit] Personal life

[edit] Legal issues

On December 9, 2007, Way was sued by William Lyons (a.k.a. Souljah Boy of Mo Thugs Family) who created the stage name "Souljah Boy" in 1996.^[49]

On October 7, 2009, Way was arrested in Atlanta, Georgia on one count of obstruction, a misdemeanor, for running from police when he'd been ordered to stop while filming a video in an abandoned house. The rapper was released on $550 bond.^[50]

In May 2011, Way and his labels were sued by a local Pennsylvania promoter for failing to make promised payments in connection with a rescheduled concert.^[51]

On October 18, 2011, Way was traveling west on I-20 in Carroll County, Georgia with four other men when their vehicle was pulled over for a vehicle equipment violation. The police officer who made the stop searched the vehicle and found more than five ounces of marijuana. Way was arrested and released on bond during the same day.^[52]

[edit] Victim of robbery and battery

On December 30, 2008, Way was robbed and battered in his home. Initial reports indicated that the robbers were six masked men with AK-47s and pistols but on December 31, 2008, video clips surfaced on the Internet of two masked men claiming sole credit for the crime.^[53] Soulja Boy described the incident to MTV News a month later: He had come home very late at night after attending an album release party and was recording songs with friends when the robbers came in pointing their guns.^[54]

[edit] Family tragedies

On the night of March 22, 2011, Way's little brother Deion Jenkins was killed in a car crash.^[55] Then on March 24, 2011 Way's older brother threatened to commit suicide.^[56]

[edit] Controversies

Way's music has been banned from some school dances for sexual or violent content and/or innuendos. However, he has denied these claims.^[57] In the original YouTube video for "Shootout", Soulja Boy demonstrates his dance while holding a handgun in each hand and pretending to shoot into the audience.^[58]

[edit] Nas

On February 25, 2008, Way said in an interview that "Nas killed hip hop and his own career".^[59] Way later apologized for his comments.^[60]

[edit] Ice-T

In June 2008, on DJ Cisco's Urban Legend mixtape, Ice-T told Way to "eat a dick" and criticized Way for "killing hip-hop" and his song "Crank That" for being "garbage" compared to the works of other hip-hop artists such as Rakim, Das EFX, Big Daddy Kane and Ice Cube.^[61] The two then traded videos back and forth over the Internet.^[62] Rapper Kanye West defended Way by arguing that the younger artist created a new, original work for hip-hop, thus keeping the authentic meaning of the music.^[63] The feud was parodied in a 2010 episode of The Boondocks.

In May 2011, Way's feud somewhat reignited with Ice-T again regarding The film Juice. Way stated he would also released a movie of his own to go along with his mixtape of the same name again somewhat reignited with Ice-T following a statement during Ice-T's interview with Shade 45 in late April 2011. Ice-T stated that Way's role as Bishop, which was famously originated by Tupac Shakur was not an issue. But Ice-T would find the fact that the film being remade is problematic saying ""What?” he said. “But that’s Pac… At some point, somebody gotta stop it. I came out. I made some statements. Man, I don’t know. Do you, dude, do you. If the masses accept it, it shows you the state we’re in… Come on man, you think I’d try to remake Pac’s movie? Good luck though, I'm not a hater...eh." Way himself barraged Ice-T with retaliatory tweets on the same day, joking that someone should "get this guy a hairline." ^[64][65]

[edit] Charles Hamilton

On December 9, 2008, Charles Hamilton commented in a interview by saying that Way was making it harder for new artists to be signed.^[66] Way responded by saying "X out the Sonic and fuck with Mario, you might want to got damn eat a mushroom."^{[67][further explanation needed]} Charles Hamilton responded with the diss song "I'm You Last Year With Talent".^[68] Then the diss song "Word Aight".^[69]

[edit] Bow Wow

On February 2, 2009, Way challenged Bow Wow to a race in their Lamborghinis and claimed Bow Wow's Lamborghini was a rental.^[70] On February 4, 2009 Bow Wow proved that he owned his Lamborghini and said "its halloween in Bankhead for you everyday nigga..you scared..you all nervous and shit". Way responded on twitter by saying "HE FUCKED UP!!!! IM BOUT TO SHITTTT ON THIS NIGGA!! LOL!!!!!".^[71] On February 7, 2009 both artist sent diss songs to each other such as Way's "Fuck Bow Wow" & Bow Wow's "What I Think About You".^[72] Later that day during a phone conversation both rappers settled their differences.^[73]

[edit] Fabolous

On December 28, 2010, Fabolous during a radio interview commented on the claim that Way does cocaine, saying "pretty boy swag but never coke my nose though",^[74] a reference to Way's song "Pretty Boy Swag. "Soulja Boy went on a tirade^[75] on Twitter in response, saying "I ignore dis foo like 5x before this. fuck that. If you send some niggaz to spray me @myfabolouslife at least I die I real nigga fuck you boy." 50 Cent also took to Twitter to say, "leave him the f*** alone before somebody get hurt." Way and Fabolous ended their beef on a radio interview.^[76]

[edit] U.S. Military

In September 2011, Soulja Boy released the song "Let's Be Real". One of the lines of the song went: "Fuck the FBI and the army troops ... fighting for what? Be your own man ... I'll be flying through the clouds with green like I'm Peter Pan."^[77] After the song was released, Soulja Boy was highly criticized by the military members and their families, especially in regards to the timing relative to the 10th anniversary of the 9/11 attacks.^[78][79][80] Soulja Boy apologized, "When I expressed my frustration with the US Army, not only did my words come out wrong, I was wrong to even speak them." He adds, "So, I write this to give my sincerest apology to all members of the United States military services, as well as their families that were offended by my most recent lyrics."^[77] Representatives for Soulja Boy have indicated that the song has been pulled from his upcoming album, Promise, and will not be available for sale. They are also attempting to remove the video from the internet.^[81]

On September 7, 2011, the New York Times cited the U.S. military has announced an official ban on Way's music. Way apologized for the content of the song and has offered to do free performances for American soldiers.^[82]
