Lecture 5 Blog, ECE438 Fall 2011, Prof. Boutin

Wednesday August 31, 2011 (Week 2) - See Course Outline.

In the fifth lecture, we continued talking about the z-transform. We noted that there are signals for which the z-transform exists but the Fourier transform does not. We introduced the notion of "region of absolute converge" (ROC) for the z-transform and observed the fact that it consists of circles around the origin of the complex plane.

The homework was collected. Apparently, few people have the correct answers. I thus urge you to work on the following collective problem:

I have also created a practice problem for those of you who are not comfortable writing equations on Rhea.
