New idea for a Shepard Function Generator....

[Martin Czech]

Your proposal sounds pretty complicated. As far as saw waves are needed
I have seen a saw "phase shifter" , was it in ETI? It was intended to
beef up a single saw vco and could deliver a couple of phase shiftet
saw with the same frewquency.  A pulse wasve was added to the incomming
saw, one edge in the middle (controlling the shift) and the other edge
always at the saw discharge. This way a shiftet saw wave is computed,
the pulse is generated via control voltage and a comparator and the
incomming saw. I think you can easily understand the opration with a
pencil and a piece of paper.

The only problem I can see are glitches and/or jumps. Since the pulse
edges/discharge are much faster then the saw slope, maybe they could be
filtered out.
