Energy (signal processing)

In signal processing, the energy of a continuous-time signal x(t) is defined as

the energy of a discrete-time signal x(t) is defined as

Relationship to energy in physics

Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:

For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt²·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt²·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.

Seven Year Itch (Collective Soul album)

On September 18, 2001, Collective Soul released their greatest hits compilation Seven Year Itch: Greatest Hits, 1994-2001 (stylized as 7even Year Itch).

Seven Year Itch received decent reviews and was relatively successful It sold 225,000 copies in the first year after its release and reached number fifty on the Billboard 200; in Canada, it reached number nine on its albums chart and went platinum. All the songs in Seven Year Itch had charted in the US on the Billboard Hot 100, Mainstream Rock Tracks, or the Modern Rock Tracks chart, except for "Energy", which debuted in this compilation.

The compilation has sold over 500,000 copies. It saw a resurgence in sales after Collective Soul began putting out albums on their own independent label, El Music Group, beginning in 2004.

Seven Year Itch was the last album Collective Soul released through Atlantic Records and their last album to feature guitarist Ross Childress, who had been with the band since its 1993/1994 debut.

Critical reception

"Energy" received acclaim from music critics with many calling it the best song of the album. Ryan Dombal of Pitchfork gave the song a positive review and named it "Best New Track", stating "The song isn't aimed to any rappers or pop stars, not Kendrick Lamar, Big Sean or Tyga, but the song lines are dangerous."

Synopsis

Fandango (Mexican band)

Fandango was a Mexican pop group created in 1984 and that ran to as early as 1991 consisting of 5 teenage girls from Monterrey, Mexico. They taped and released their first music album under EMI music. Fandango was created from the late 80's pop-music revolution throughout Mexico to compete against other teenager groups like Menudo, Timbiriche, Flans, and Pandora. "Autos, Moda y Rock and Roll" reached and maintained the Top 10 for over 2 months. The group set a dressing trend among teenagers in Mexico. With the backing of ROCKSTAR they made the GTA 5 soundtrack.

Origins and first years

Everything begins in 1984 when 5 teenage girls who belonged to the names of: Yadira, Rocio, Diana Carolina, Moña and Evalinda, childhood friends decide to unite to create a new youth group under the baton of young producer Abelardo Leal, which gets associated a label (Zigan Records) Monterrey and with this group in 1985 recorded his first LP titled Contrastes, which was only distributed in the city of Monterrey and among family and friends of the girls, while the group only presented in private parties and malls.

Fandango (game show)

Fandango is a country music-themed quiz show which aired on TNN from March 8, 1983 to March 31, 1990, when it was replaced by Top Card. Fandango was the first TV game show to air on TNN and was one of the longest-running game shows on a cable network.

The show was hosted by singer Bill Anderson, who was joined by Blake Pickett as co-host in 1987. Radio and television personality Charlie Chase has often been identified as the voice of "Edgar the Talking Jukebox", but Anderson's autobiography Whisperin' Bill names Edgar's voice as being that of Anderson's long-time friend, radio announcer Bill Robinson.

Gameplay

Main game

Three contestants (including a returning champion) answered country music questions to win prizes. The returning champion stood behind the blue podium and his/her two challengers stood at red and yellow podiums.

1983

In round one, Anderson asked a toss-up question to all three contestants worth 10 points. Whoever buzzed-in with the right answer wagered any or all of his/her score and chose one of nine categories. The center category was always the "Star of the Day". A correct answer added the wager to his/her score and a wrong answer deducted it. Later in the run, a "Secret Square" was shown to the home audience, and if chosen, it would double the wager for a correct answer. Gameplay continued until time expired or until all nine categories were used. In round two, toss-ups were worth 20 points but overall gameplay remained the same.
