In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. This contrasts with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency remains constant.
In analog frequency modulation, such as FM radio broadcasting of an audio signal representing voice or music, the instantaneous frequency deviation, the difference between the frequency of the carrier and its center frequency, is proportional to the modulating signal.
Digital data can be encoded and transmitted via FM by shifting the carrier's frequency among a predefined set of frequencies representing digits - for example one frequency can represent a binary 1 and a second can represent binary 0. This modulation technique is known as frequency-shift keying (FSK). FSK is widely used in modems and fax modems, and can also be used to send Morse code.Radioteletype also uses FSK.

Plot: It's another day. It's another day at the factory, another weekend, another Friday night, and another stop at the local all night breakfast and coffee joint. F.M.'s life has cemented itself in a rut. He serves the same idiotic warehouse, he lives in the same room at his parents, and all of the same co-workers drive him nuts. But then he sees her, and his life is never the same again. She is the Sexy Chef, a woman F.M. only briefly observes smoking in a seedy alley behind a local culinary institute. Transfixed by her image, the Sexy Chef becomes F.M.'s one last hope, the guiding light on an epic road-trip. He is joined by his friends: Tank, a crude, unemployable slacker, Paul, a quiet misanthrope, and Wynonna, Tank's half-sister and practicing witch. Together, they track the elusive and alluring Chef. The road is long and strange. F.M. is haunted by his old couch. The group is given direction from prankster spirits from beyond. Bizarre Saturday morning cartoon fetishes come to light. F.M. needs to be rescued from a tree while a naked metal patient throws hamburger buns at him. All the while the group stays one step behind the chef. At the end of the line, the weary travelers find themselves at a Casino, where each discovers their individual destiny. It is at the Casino that F.M. finds the Chef. Naturally, nothing goes as planned. F.M. ends up alone, stranded in the desert, without his car, or friends. However, he does finally understand what must be done.

Highly edited version of US Army training video (TF11-3482 - Frequency Modulation Part I: Basic Principles, 1964) on the basics of FM transmission. This also shows how AM works. For educational purposes for my students.
Hello Students, In this video I have covered an important topic from examination point of view of COMMUNICATION SYSTEM(FREQUENCY MODULATION). In this lecture I discussed about the Angle Modulation concept and one of its important part i.e Frequency Modulation. In frequency modulation I discussed about single tone frequency modulation and some general concept about it. This topic is important for the formation of COMMUNICATION SYSTEM and many questions were asked in BSNL JE(TTA) and JTO and other Competitive Examination during the last years. KINDLY SHARE,SUBSCRIBE,AND LIKE to show your support. Thanks BSNL TTA | BSNL JE | BSNL TTA(JE)-2016 | COMMUNICATION SYSTEM| MODULATION| DEMODULATION|FREQUENCY MODULATION | ELECTRONICS DEVICES AND CIRCUITS |BSNL JTO | PSU | GATE | ENGINE...
Demonstration of Frequency Modulation Radio Teacher Project From HamElmer at http://HamElmer.com
This is the first of 3 videos covering frequency modulation and the Operator synth. This Was made in a previous version of Operator but the concepts and techniques are still very valid. These videos were made to go along with my Advanced Production in Ableton Live, but didn't make it into the course, so I thought everyone could benefit here on youtube and my blog( http://loudonstearns.berkleemusicblogs.com/ ) instead!
The principles of frequency modulation (FM), the circuitry, and the difference between AM (Amplitude Modulation) and FM
A 3 min demonstration of Frequency Modulation and Deviation. Applies to Amateur Radio operators who transmit on the VHF and UHF bands. Also to those studying for their Technician License. This is what is going on when you Transmit on your hand held or mobile radio. Demonstration by Bill Nevill WA7KMF. Videotaped and edited by Kevin Reeve N7RXE
Worry the bottle mama, it's grapefruit wine
Kick off your high heel, sneakers, it's party time
The girls don't seem to care what's on, as long as they play till dawn
Nothin' but blues and Elvis, and somebody else favorite song
Give her some funked up music, she treats you nice
Feed her some hungry reggae, she'll love you twice
The girls don't seem to care tonight
As long as the mood is right
No static at all
(No static, no static at all)
