FM:

Frequency modulation (FM) means that the frequency of the high-frequency carrier is not a constant, it is a modulation method that varies within a certain range with the modulation signal, and its amplitude is a constant. Correspondingly, the amplitude modulation is that the frequency of the carrier frequency is constant, and its amplitude varies with the modulation signal.
