WebPhase 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. The frequency-domain effects of phase modulation are similar to those of frequency modulation. WebFeedback.
