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


Presumably that depends on how "suitably noisy" your diode is, and how fast
your Schmitt trigger is.

Here's a project for you: how can you describe the behavior of a
(real-world) Schmitt trigger in the frequency domain, that is, in terms of
how it affects a signal's frequency spectrum?

To put it technically, "they generate loads of harmonics" - a perfect
one presumably an infinite comb of harmonics? Am I near the mark?
