Linear Systems and Signals, 2e, presents a clear, comprehensive introduction to signals and linear systems. The book emphasizes physical appreciation of concepts through heuristic reasoning and the use of metaphors, analogies, and creative explanations. Such an approach is much different from a purely deductive technique that uses mere mathematical manipulation of symbols and ignores the physical meaning behind various derivations. The deductive technique deprives students of the enjoyable experience of logically uncovering the subject matter. Here the author uses mathematics not so much to prove axiomatic theory as to support and enhance physical and intuitive understanding. Wherever possible, theoretical results are interpreted heuristically and are enhanced by carefully chosen examples and analogies.

The organization of the text allows for a great deal of flexibility in teaching continuous-time and discrete-time concepts. The natural order of the chapters in the book integrates the two: however, the book can also be tailored to teach these concepts sequentially.

Its thorough content, practical approach, and structural adaptability make Linear Systems and Signals, 2e ideal for undergraduate courses in linear systems or in signals and systems.
