That's promising.  I'm thinking of just a bit of code that gives
a bitwise accurate model of the datastream, matching to the timing of the analog
model in gnucap as test benches do in logic models.

Just to test out your combination
of sigma delta front end quantizer and numerical filter together, for instance.
for "sensorless" motor control and such.
