[sdiy] CV Quantizer

[Harry Bissell Jr]

Its 'almost' as easy as that. The secret to making it
work well, is to run the output of the CV comparator
(1st TL072 in the lower schematic) into the "D"
input of a CD4013, and clock the 4013 with the other
phase of the 25KHz clock

(so the counter increments on one edge of the clock.
and the 4013 latches the data on the other edge of the
clock)

This allows a little time for the voltage to be stable
before the S/H locks in the voltage.

I have built this one, It works 'ok' without the 4013
and great with it !
