FM


 * This is about the radio technology. For magnetic disk encoding see FM encoding. For the Creative FM Blaster format, see FM (Creative FM Blaster).

FM (Frequency Modulation) is a method of broadcasting that carries information by modifying the frequency of the broadcast, in contrast to AM (Amplitude Modulation) which varies the amplitude. The term is also used for other encoding techniques that vary frequency, including FM encoding for magnetic disk storage.
