What is the modulation index of PM?
Phase modulation is calculated by adding the baseband signal to the argument of a sine or cosine function that represents the carrier. The modulation index makes the phase variations more or less sensitive to the behavior of the baseband signal.
What is PM frequency?
Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. Phase modulation is one of the two principal forms of angle modulation, together with frequency modulation.
Is PM analog modulation?
Phase modulation, PM is sometimes used for analogue transmission, but it has become the basis for modulation schemes used for carrying data. Phase shoft keying, PSK is widely used for data communication.
