In Lecture 11, we talked further about sampling, wuth an emphasis on the reconstruction of signals from their sampling. In particular, we obtained a band-limited reconstruction obtained using Whitaker-Kotelnikov-Shannon expansion. We then begin talking about the relationship between the Fourier transform of a signal x(t) and that of the sampling
$ x_d[n]=x\left(nT\right). $
