LINEAR SYSTEMS AND SIGNALS

COURSE DESCRIPTION
The concepts of Signals and Systems arise in a wide variety of fields such as telecommunications, acoustics, image and speech processing, computer communications, and biomedical engineering. Signals carry information about the nature of some physical phenomena such as electrocardiograms which contain information on the heart rate and heart dynamics. Systems respond to input signals and produce other signals as their output. In some applications, the signals vary continuously in time or space, whereas in others, their evolution is described only at discrete points in time. Because of the growing interrelationship between continuous-time and discrete-time signals and because of the close relationship among the concepts and techniques associated with each, we will cover both types of signals together.
