WebFrequency modulation and phase modulation are the two complementary principal methods of angle modulation; phase modulation is often used as an intermediate step to achieve frequency modulation. These methods contrast with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency and phase remain constant. WebAM (or Amplitude Modulation) and FM (or Frequency Modulation) are ways of broadcasting radio signals.Both transmit the information in the form of electromagnetic waves. AM works by modulating (varying) the amplitude …
