Everyone who has any interest in effective communications should
study what Claude Shannon summarized. It is absolutely
fascinating to read.

Wow, that brings back memories! The Shannon Day conference/celebration
was quite an interesting event. Now I'm going to have to dig through my old
files for that packet of papers.


[2] Probably best at this point not to start worrying about distortion as
being 'signal' or not... ;-

Can it contain information?

Distortion can *always* be counteracted by the introduction of
an "error signal" which is opposite to the distortion.
Therefore it would seem that distortion is necessarily a signal
in all cases.

I'd tend to say that distortion adds to noise side of the SNR, and
some can be corrected ...but *always* ? Let's say the distortion
is the result of clipping...
