Lecture 11 Blog, ECE438 Fall 2011, Prof. Boutin

Friday September 16, 2011 (Week 4) - See Course Outline.

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). $
