selection</DIV>
<DIV><BR></DIV>The problem w/ the circuit is that it doesn't sample... I
think... Sometimes I get a super high pitched am radio out of tune sort
of sound. Then, if I touch the transistor I can get it to sample and
hold... each time I touch the transistor it samples again... BUT.. the
sample goes from that super high pitched sound to such low frequency that the
VCO I have it hooked up to simply pulses.. The input is hooked up
to another VCO, so Im not sure if its really sampling the input... I wouldn't
think I'd get such strange frequencies.<BR><BR></BLOCKQUOTE></BODY></HTML>
