Discrete BBD

[harry]

I've quoted Father Guido Sarducci (referring to 'peas on a cob') as saying
"Its like taking something that tastes bad... and making it hard to eat too...."

(of course my BBD opinions are my own, and well known...)

You might do a discrete... you would have the advantages of control of each stage...
if you used high quality analog switches you might even get Bipolar signals through it,
and you'd possibly have +- 15 volt supplies...

OTOH unless you were thinking of hundreds of stages... probably not worth it.
For the same money / time ... you could do a really good A/D memory D/A and
have a "digital delay"

I have thought of a chain of S/H for control voltages, this might be interesting especially
for things like guitar pitch to voltage conversion, where sometimes the most recent sample
is also the WRONG sample....
