[sdiy] new project in the works

[Czech Martin]

I think the original idea was to quantize levels,
but not time. So no alias effects.
But perhaps other time related effects (e.g. slew rate).

How can you describe the effects you got
without much alias involved?

m.c.

I built one of those some years back with a different approach. I used a
PIC16 to sample the incoming signal to 8 bits, then mask the result to 1
through 8 bits. I could also control the sampling rate from 36kHz down
to 1kHz. This gives a ring modulation effect due to the Nyquist effect.
The two parameters (bit count and sample rate) were set by two voltages,
directly sampled by the PIC. So you could call it voltage controlled.
