    Introduction to Frequency Modulation (FM) Frequency Modulation (FM) is a method of impressing data onto an alternating-current (AC) 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 applications, the instantaneous frequency of the carrier…
