Lecture 6 Blog, ECE438 Fall 2011, Prof. Boutin

Friday September 2, 2011 (Week 2) - See Course Outline.

In Lecture 6, we learned how to compute the inverse z-transform and worked out a bunch of examples. We also pointed out an important property of the ROC of the z-transform, namely that causal signals have ROCs that are either

• the whole complex plane, or
• the outside of a circle centered at the origin in the complex plane, or
• the empty set.

Relevant Rhea Pages:

• A guide to Partial Fraction Expansion

Action items:

• Continue working on the second homework. It is due Wednesday (in class).

Note: I will not be adding any new practice problem to the course wiki this time.
