Why do you you think a simple detect/invert/sum analog process needs "very
regular and predictably structured noise?"
The ones I've used work well with random noise.
If you add two random noises, you just get more random noise.
By definition, random isnt correlated with anything else, especially
other random sequences.
Without exact algebraic correlation, you can't subtract and get a
Now you can clip, divide, or blank impulse noise, but that's not noise
in the hissy sense. It's reliably short and spiky and above the
desired signal level, making it reliably detectable. You can't do
the same for hissy noise, by definition. If you could, then we'd be
able to pick up several million TV stations from other galaxies with
just a tea saucer covered with tn foil.
