Frequency modulation (FM) is the encoding of the information in a carrier wave by varying the instantaneous frequency of the wave. It is in the field of telecommunications and signal processing, that this kind of technique is mostly used. FM is in contrast with amplitude modulation where amplitude of the carrier waves is modulated with frequency remaining unchanged and constant.
