Hi Terry, All,

This is very hard for me to envision. Seems like at 2* res, the cap would 
charge to V/2 on the first quarter cycle then discharge to zero on the 
second quarter cycle and then, because of the reversed polarity, charge to 
V/2 in the reverse direction, etc., giving zero BPS. It also seems that if 
the bps is not a multiple of the supply frequency, you may get, say, 200 
BPS, but they will not be uniformly spaced or of uniform duration. Am I 
missing something?
