Hi Dave,

I'm sure you know that a pure sine wave would have no harmonics, so it
seems to me that you would have to know how it was being distorted in
order to know what harmonics are present. I suppose you could make the
argument that many types of nonlinearities tend to have the effect of
applying an x^2 function to the waveform, thereby introducing mainly 2nd
harmonics, but I wonder how generally that applies.
