Features: Based on undergraduate-level signals and linear systems, this book systematically explores the fundamental theories and methods of signals and systems analysis using relatively advanced mathematical approaches. It aims to establish a foundational platform for postgraduate students in electronic, control, and information disciplines, focusing on engineering and master's programs. The book is divided into five chapters. Chapter 1 serves as a bridge to undergraduate content and lays the groundwork for the entire book, reinforcing students' integrated understanding of the physical concepts and mathematical methods of signals and systems analysis. Chapter 2 delves into the dual nature and transformation unity of discrete signals, providing a profound understanding of the essential connection between time-domain and frequency-domain descriptions of signals, thereby expanding the methods of signal analysis. Building on transformation unity, Chapter 3 systematically examines the principles and methods of Fourier analysis. Chapter 4 discusses the fundamental theories and methods of system analysis using the principle of moment expansion, with a focus on the implementation methods of important functional modules in information systems, as well as the analysis of basic system characteristics. Chapter 5 explores the fundamental principles and key properties of digital processing and approximation for analog signals and systems, enabling students to master the digital approximation and design methods for analog systems. The book strives to be both rigorous and accessible, with clear explanations that emphasize the integration of physical concepts, fundamental theories, and basic analytical methods. It includes a selection of carefully chosen examples and exercises at the end of each chapter. This book is suitable for postgraduate students in electronic information disciplines, as a textbook or reference for engineering master's programs or elective courses, as well as for relevant instructors and engineering and technical personnel.
