3.9 Phase Modulation (PM)
Introduction
A modulated waveform consists of a carrier waveform and a modulating
waveform. PM is very similar to FM, but in PM the phase of the modulated
waveform is varied by the instantaneous voltage of the modulating
waveform.
For more information on the fundamentals of Phase Modulation, refer to the
Tutorial chapter.
