FFT, Phase Modulation.

Cuthbert Nyack
Applet shows the FFT of an PM signal with carrier frequency w1, modulating frequency w2 and modulating index m.

This signal differs from FM because the bandwidth depends on the modulating frequency as well as the modulating index.
Changing Fn shows PM for a triangle and a ramp.
