# Lecture 8 Blog, ECE438 Fall 2011, Prof. Boutin

Friday September 9, 2011 (Week 3) - See Course Outline.

In Lecture 8, we presented the formula for the inverse z-transform and illustrated its use on a very simple example. We concluded that using the formula essentially boils down to comparing the power series of the z-transform with the formula for the z-transform (the trick we presented earlier). We discussed three important properties of the z-transform and gave a mathematical proof for one of them. We finished the lecture by beginning another example of computation of the inverse z-transform.
