Today we continued talking about Nyquist Theorem. After stating Nyquist theorem in different ways (taking the general point of view that the sampling is obtained by multiplying x(t) by some repeated function g(t)), we proved Nyquist theorem. We then began talking about how the reconstructed signal looks in the time domain. In particular, we derived an explicit expression for the reconstructed signal.
