I think you might be missing Andy was saying here - and this is a very
important point - that you don't get to decide where on the wave you
It just happens on a regular schedule. It could easily happen that
sampling exactly on the zero crossing of that wave who's frequency is 1/2
the sample frequency. What sound informaton do you have then? nothing.
you are lucky enough to be sampling right on the peak and valley, then
you'll get a triangular wave. If you happen to sample somewhere between
the zero crossing and the peaks, then you'll get a sawtooth that is much
less volume and out of phase.
