thanks alex for the technical explanation, it is exactly what i thought was the case.
i did indeed use rx (mac) in the manner you've outlined. once i learned the
true reconstructed signal values, it was an eye opening and educational
experience for me. the values were way outside of my expectations.
in fact it was reminiscent of figuring out that santa claus does not exist.
most kids play along for a while after they discover the truth because
it is to their benefit, in the end though, poor kids get nothing.
that was the hardest part to admit. well.. there may be no
santa... but -they- have a "santa", don't they? sadly, no.
