Thanks to Ed Carryer for the PWM lesson

[Nelson David E]

Ed Carryer:
	Your explanation and example were wonderful, thank you.  I had 
thought of doing a little bit of system modeling on the mechanical device 
but in your explanation it sounds as if I could measure the output to 
select the desired pwm frequency and be done with it.
