David,.. the issue is predistortion...... or appears to be....  You mess up
the input before sampling so that the output of the sampler is correct.

A similar concept to noise cancellation in helicopter noise reducing
headphones ( I think this is also done on the Cadillac or BMW or Mercedes
cars as well... using the radio as the output noise maker).......  Also used
in modern Modems......

Yes, I did study Nyquist theroy and I am very familiar with it.  It is one
of the reasons I do not accpet ( easily?) the Schneider story... Still
sounds like marketing theroy.
