# Lecture 7 Blog, ECE438 Fall 2011, Prof. Boutin

Wednesday September 7, 2011 (Week 3) - See Course Outline.

In Lecture 7, we finished discussing the properties of the ROC for causal, anti-causal and mixed-causal signals. We also had a lengthy discussion about infinity in the complex plane, and mentioned that z-transforms may or may not converge at infinity. No, there is no homework this week. But I expect each and everyone of you to work on the practice problems.
