An Introduction to Signals and Systems

"This book provides a concise and dear introduction to signals and systems theory, with emphasis on fundamental analytical and computational techniques. An Introduction to Signals and Systems develops continuoustime and discrete-time concepts/methods in separate chapters—highlighting the similarities and differences—and features introductory treatments of the applications of these basic methods in such areas as filtering, communication, sampling, discrete-time processing of continuous-time signals, and feedback. This text is written for introductory courses in continuous-time and/or discretetime signals and systems for Electrical Engineering students. It is also accessible to a broad range of engineering and science students, as well as valuable to practicing engineers seeking an insightful review."
