COURSE AND LABORATORY DEVELOPMENT

A signal processing lab has been developed and used in the undergraduate level Signals and Communication Theory courses and the graduate level Digital Signal Processing course at the University of Rochester, as well as at North Dakota State University. An interactive software package (written in C) has been developed for use in the lab as an aid for the analysis and design of analog and discrete-time linear systems. Discrete-time systems are implemented in real-time using a Texas Instruments TMS32010-based system. A text, {\em Fundamentals of Signals and Linear Systems}, is being written based on lecture notes developed for the undergraduate Signals course at the University of Rochester. Discrete-time and analog signals and systems, corresponding transforms, sampling theory, and complex variable theory are included. Another text, Applied Probability and Random Processes for Electrical Engineers, is being written with J. D. Enderle and D. J. Krause.
