Fm vs pm modulation

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. WebJul 12, 2024 · Difference between Frequency Modulation and Phase Modulation. 1. Frequency Modulation: Frequency Modulation is a modulation in which the frequency of the carrier wave changes according to the instantaneous amplitude of the …
