Lecture 20 Blog, ECE438 Fall 2010, Prof. Boutin
Friday October 8, 2010.
Having defined DT systems in the previous lecture and described some basic system properties, we focused our discussion in this lecture on Linear-Time-Invariant (LTI) DT systems. We listed some important properties of such systems, which led us to the concepts of "Frequency Response" and "Transfer function" of a system. We then defined a simple filter with low-pass characteristics (Filter A) and another filer with band-pass characteristics (Filter B). The behavior of these two filters will be further studied when we return from Fall Break. Enjoy your time off!
