Frequency modulation is widely used for FM radio broadcasting. ... In radio transmission, an advantage of frequency modulation is that it has a larger signal-to-noise ratio and therefore rejects radio frequency interference better than an equal power amplitude modulation (AM) signal.

Why is FM used for audio transmission?

Frequency modulation (FM)

Because the frequency of a radio wave is less vulnerable to noise than the amplitude, FM was originally introduced to reduce noise and improve the quality of radio reception. ... FM, though, because of its relative noise-free reception, is used to transmit the audio part of the television signal.

What are the applications of FM?

The applications of frequency modulation include FM radio broadcasting, radar, seismic prospecting, telemetry, & observing infants for seizure through EEG, music synthesis, two-way radio systems, magnetic tape recording systems, video broadcast systems, etc.
