[sdiy] bucket brigade circuit

[Harry Bissell Jr]

Since you want to decimate (lol) there is little
reason to go beyond 8 bits of resolution.

If you take an A/D converter with parallel output, and
attach it to a D/A converter with parallel input, that
would work.  You will need to either use really fast
converters, or have some lowpass filters at the input
AND output (probably you need to do both).

Run the digital signal through some toggle switches so
you can either send the bits from the A/D to the D/a,
or ground the D/A inputs instead.

One easy solution would be the Wiard/Blacet
MiniWave...
you could program the EPROM to allow the decimation
and it already has all the circuity you need, you
could voltage control the amount of bit reduction

They might already HAVE this programmed
