Principles Of Linear Systems And Signals

0.0

The international version of the second edition of Principles of Linear Systems and Signals presents a clear, comprehensive introduction to signals and linear systems. The book emphasizes physical appreciation of concepts through heuristic reasoning, metaphors, analogies, and creative explanations. Such an approach is different from a purely deductive technique that uses mere mathematical manipulation of symbols and ignores the physical meaning behind various derivations. This deprives a student of the enjoyable experience of logical uncovering of 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 the international version of Principles of Linear Systems and Signals, Second Edition, ideal for undergraduate courses in linear systems or signals and systems. New Topics Fourier applications to communication systems Bode Plots Bandpass systems Convergence of an infinite series Group and phase delay Impulse invariance method of designing analog systems using digital filters Key Features Offers MATLAB® focus sessions at the end of each chapter Provides updated and revised illustrations throughout Presents historical background notes to stimulate interest in the field
