Features: This book studies the fundamental concepts and basic analytical methods for the transmission and processing of deterministic signals in linear time-invariant systems. The research objects involve both continuous-time and discrete-time domains, while the research methods include time-domain analysis and frequency-domain analysis, with a focus on frequency-domain analysis. The book is divided into 7 chapters. Chapter 1 discusses signals, signal operations, and convolution. Chapter 2 discusses linear time-invariant systems and their basic properties. Chapters 3 and 4 are discussed in parallel, covering the basic theories and methods of continuous-time Fourier transform and discrete-time Fourier transform, respectively. Chapter 5 discusses the application of Fourier transform in filtering, modulation, and sampling. Chapters 6 and 7 discuss the Laplace transform and z-transform, with a focus on the application of system functions in system analysis. To enhance ability development, compared to similar textbooks, this book includes additional comprehensive guidance and supplementary reading materials. Each chapter features selected examples and exercises of different types, and reference answers to the exercises are provided at the end of the book. This book can serve as a textbook for university-level courses on signals and systems, as well as a self-study reference for scientific research and engineering professionals.
