[sdiy] Upper frequency limit for VCO

[Scott Gravenhorst]

If the idea is to replicate the original VCO waveform in all of the divided
outputs, wouldn't it be easier to use frequency doubling waveshapers and
start at the bottom instead of starting at the high end and using dividers?
 I've seen frequency doubling circuits for tri and saw inputs.  AFAIK,
divider outputs are rectangular which doesn't lend well to waveshaping back
to saw or tri.  However, if you _want_ rectangular, that's easy to divide
and you could also investigate Walsh functions.
