Hi,Yes definitely seeing Gibbs. I doubled the frequency of everything
and am out to the 27th odd harmonic now. Base frequency of the
square is 1050Hz and this goes on out to 28350 Hz. Frequency of
the little sine wave is 5Khz. The ratio of the two is 4.762. The
ratio is a tiny bit higher than what the paper calls for, but
I need it that way to get coherent sampling on the FFT. I checked
to make sure I can see harmonics of the sine falling between the
cracks of the *vast sea* of IM products which are *towering* above
the sine harmonics.Just looking at this I can't help but observe: The IM looks more
like a 1st order problem, while the TIM is maybe 2nd order?
