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 discuss the fundamental theories and methods of continuous-time Fourier transform and discrete-time Fourier transform in parallel. Chapter 5 discusses the application of Fourier transform in filtering, modulation, and sampling. Chapters 6 and 7 discuss Laplace transform and z-transform, with a focus on the application of system functions in system analysis. To enhance ability development, this book includes comprehensive guidance and supplementary reading materials, which are more extensive than those in similar textbooks. Each chapter features carefully selected examples and exercises of different types, and reference answers to all chapter exercises are provided at the end of the book. This book can be used as a textbook for signal and system courses in higher education institutions, as well as a self-study reference for scientific research and engineering professionals.
