I pose the following question.  Suppose you are sampling at rate N samples
per second, and you see a constant value V for your A/D sample.  Is the
frequency of the signal which produced those samples 0 or N/2?  Since
I obviously posed this question because I know you CANNOT discriminate
between these two cases, what exactly is it then that Nyquist IS telling
us and am I asking about apples and oranges?
