That gives me an idea, Walter... How about I amplify the white noise
from a suitably noisy diode and feed it through a Schmidt or something
similar? What sort of harmonic richness would that give me?

I'm sorry, but I've not been keeping track of what kind of problem you're
trying to solve. It sure sounds like you're trying to reinvent some sort of
wheel here, though.

If you are trying to start with a noise source in order to generate a signal
at a specific, adjustable frequency, then surely you must consider that the
way to do that is to filter the noise source; and that the task of making a
good tuneable filter is no different than the task of making a good tuneable
oscillator. And starting with broadband noise is not generally a good
approach to getting something quiet.

I know. This is purely hypothetical. What sort of spectral range would
one get from this idea?
