waveform conversion

[Arthur Harrison]

Hi Scott and everyone,

I don't specifically recall what the settling time for my
square-to-triangle converter is.

I will try to find the original breadboard, which might
still exist (its been about 10 years since we did this work).
If I can find it, I'll try to scale the time constants
down to a useful audio range, and see how it sounds.
Then, if it remotely seems to have any merit for synth
applications, I'll put it up on my page.

I have a huge backup of work right now, so it may take a
long while.

The circuit was developed as part of a communications
system, so I really don't know of its merits for music
applications.  However, it is an interesting scheme, and
points to the value of servos in analog applications.

-Art
