Lecture 11 Blog, ECE438 Fall 2010, Prof. Boutin

Friday September 17, 2010.

In Lecture #11, we talked further about the reconstruction of signals. More specifically, we compared the band-limited reconstruction obtained using Whitaker-Kotelnikov-Shannon expansion with the band-unlimited reconstruction obtained with the zero-order hold. We then begin talking about the relationship between the Fourier transform of a signal x(t) and the sampling

$x_d[n]=x\left(nT\right).$
