Linear Systems and Signals (2nd Edition)

Linear Systems and Signals (2nd Edition)
By B.P. Lathi

Presents a clear, comprehensive introduction to signals and linear systems, emphasizing physical appreciation of concepts through heuristic reasoning and the use of metaphors, analogies, and creative explanations. This approach is markedly different from a purely deductive technique that reduces the subject to mathematical symbol manipulation while ignoring the physical meaning behind each derivation — a method that Lathi argues deprives students of the enjoyable experience of logically uncovering the subject matter for themselves. Mathematics is used throughout not so much to prove axiomatic theory as to support and enhance physical and intuitive understanding, with theoretical results interpreted heuristically wherever possible. Incorporating new problems and examples, this second edition features MATLAB material in every chapter and at the back of the book. The book provides an extensive overview of the principles surrounding signals and systems, laying critical groundwork for the quantitative analysis that follows, and is organized so continuous-time and discrete-time systems can be taught independently or together, with the focus throughout principally on linear time-invariant systems.

Topics commonly covered include:

• Signals and systems fundamentals (signal size, energy, and power)
• Signal operations (time shifting, scaling, reversal)
• Classification of signals (continuous/discrete, periodic/aperiodic, energy/power, deterministic/random)
• Time-domain analysis of continuous-time and discrete-time systems
• Fourier series and Fourier transform
• Laplace transform and z-transform
• Frequency response and filtering
• State-space analysis and system stability

Key features:

• Over 300 illustrations, 287 worked examples, and 409 homework problems
• MATLAB material integrated into every chapter
• Accompanying CD-ROM with MATLAB code, audio/image data files, interactive programs, and animations explaining convolution
• Strong emphasis on intuitive, physically grounded understanding rather than rote derivation
• Parallel treatment of continuous-time and discrete-time systems for flexible course structuring

Perfect for:

• Undergraduate electrical and computer engineering students taking signals and systems
• Students who want conceptual intuition alongside mathematical rigor
• Self-learners with a reasonable mathematics background
• Faculty teaching an introductory signals and linear systems course
