Pulse Width
Modulation
Cuthbert Nyack
This form of modulation is often used in control applications as the
average value is proportional to the pulse width. Like PAM, it is
also easy to demodulate. The spectrum is similar to that of PAM
but each line of the carrier's spectrum is now converted to something
similar to an FM spectrum.
