In a pervious post, someone brought up the theoretical problem that you
sample a sine wave with frequency f at exactly 2*f, but your first sample
is perfectly lined up at t=0. Thus it would seem that your sample stream would
then be all zeros makeing it impossible to reconstruct the original sine wave.
I have tried to reconcile this, but to no ava as of yet. Does anyone else
have any ideas on this?
