They say you can fully recover a signal if you sample it at twice the bandwidth (Nyquist rate). But how is it possible to be able to fully recover the signal since you are missing all the information about the signal between successive samples?
For example if you sample cos(2*pi*B*t) at 2B, you'd get samples which if you connected them together you'd end up with a triangular zig zag type of function, how would you know how to draw them up between the samples?
