Nope, quantization is taking the *instantaneous value* of a waveform and
using that as the representation for one sample period. That is nowhere
near the same as summing periodic square waves.

Well at least we agree that quantization is the basis of digital
representations. But I've never seen any summed square wave presentation
of it.

Well me too, but information theory is, after all, the theoretical
underpinning for the way I make my living, so I felt obliged to study it
fairly thoroughly.

Nothing personal about it. I'm just asking you to corroborate statements
you have made which, in my ignorance, I consider to be bogus hand-waving.

Nothing about you there. Just the information you are promoting. I don't
normally deal in innuendo and personal attacks. Though I do occasionally
get irritated by what I perceive to be hogwash. People who know me will
tell you, if I am wrong I will happily admit it.
