oh geez ... sorry for that typo
I appreciate your comments Dave,
I've thought of slowing down the switching transitions in the ring counter design using caps on the gates (the obvious approach) but then these would be adjusted and optimized for a specific operating speed ... it would do away with the instantaneous "chopping" effect ... but when speed variation is introduced that would all start to fail and some chopping would appear at some point in the speed range
(can't win ...)
I'm not sure how a four-quadrant multiplier would smooth out transitions either as multiplier circuits are dead fast as well ... maybe you could supply a reference to a synth circuit and I'll have a look
I'm in amp repair/modding mode these days ... in fact, working on a unique amp design that resembles nothing under the sun // ie., finishing the last unit that a good friend started before he passed ten years ago // you might have known him, or of him ...
http://www.cbc.ca/news/canada/manitoba/ ... d-1.636051
and I'm also developing a new (high headroom) optical WAH circuit ... and possibly approaching one of the big design houses with the idea of manufacturing one of my "emulator" concepts ...
a bit much on my plate right now ...
likely I'll be getting back to the CTP monster this winter
hope you're feeling better after your accident Dave ... thx for chiming in !!
best, ...
