Principles of Signal Processing and Linear

0.0

In this international version of the first edition, Principles of Signal Processing and Linear Systems, the author emphasizes the physical appreciation of concepts rather than the mere mathematical manipulation of symbols Avoiding the tendency to treat engineering as a branch of applied mathematics, the text uses mathematics not so much to prove an axiomatic theory as to enhance physical and intuitive understanding of concepts. Wherever possible, theoretical results are supported by carefully chosen examples and analogies, allowing students to intuitively discover meaning for themselves. This text presents a comprehensive treatment of signal processing and linear systems suitable for students of electrical engineering. It is based on Lathi's widely used book, Principles of Linear Systems and Signals, with additional applications to communications, controls, and filtering as well as new chapters on analog and digital filters and digital signal processing. This volume's organization is different from the earlier book. Here, the Laplace transform follows Fourier, rather than the reverse; continuous-time and discrete-time systems are treated sequentially, rather than interwoven. Additionally, the text contains enough material in discrete-time systems to be used not only for a traditional course in signals and systems but also for an introductory course in digital signal processing. Key Features An informal and reader-friendly style An emphasis on intuitive and heuristic understanding of concepts Real-life problems that solidify students' physical comprehension of concepts Nearly 200 worked examples and exercises with answers Over 400 end-of-chapter problems for practice Numerous MATLAB® problems
