WebFrequency Modulation (FM) and Phase Modulation (PM) are all forms of Angle modulation. Amplitude Modulation (AM) The transceiver produces a carrier wave at the frequency of transmission. Voice is superimposed on the carrier wave and alters its shape by changing the Amplitude or height of the wave.
