When I was in school learning about pulse techniques, I experimented on
phase modulation using pin 5 or control voltage input on a lowly 555
timer. It was amazingly clear sounding knowing it was being chopped up
into square bits. That is also when I learned about "aliasing". I kept
seeing the output waveform split up on the scope into a low frequency
component and couldn't understand why it did it until I learned about
Nyquist. Fun stuff...
