5 Chapter 1-2 AKW Fall 2010 Chapter 1 -Why is this course essential? This course will introduce to you the basic framework for the study of signals ” and “ systems Signals and systems are fundamental to all disciplines of engineering Communication theory, circuits and systems, signal processing, speech and video processing, automation and control, …. Everything we deal with can be regarded as a “system” All systems interacts with other systems through “signals” In this course, you will find a comprehensive, consistent, and elegant set of principles for the study of Linear Time Invariant ( LTI ) . These principles are fundamental to the study of many engineering problems.
