Here's a question that might help your understanding a bit:
For a given set of samples, how many possible signals (waveforms) do exist
that
1. are made up of sinusoids with frequencies up to the sample rate divided
by two, and
2. pass through all the sample points?
Answer: One.
2) Nyquist's theorem proves (and note that
I said *proves*, not
"asserts") that sampling at a given sample rate provides enough data
to reconstruct **PERFECTLY** any signal made up frequencies up to the
sample rate divided by two.
