Re: Hiraga on Feedback

Hi,

Oh. I didn't read this carefully enough. Hiraga isn't talking
about a single pure sinewave, he is talking about a complex waveform
compose of pure seperately contollable parts. I'm glad you caught
that. He is somewhat confusing because his Fig 13(A) and (B) seem
to be showing a pure sinewave and the distortion that the amp
produced from it.

I suppose that he must mean that a complex waveform run thru
a feedback loop absorbs high order harmonics of the *input* waveform?

If so, this should be a mathematical relationship. We can test
this with Spice.

I can create a complex waveform of a bunch of pure tones of various
levels and see if some of the tones get "absorbed". What sort of
complex signal do you think Hiraga is describing?
