Chinese textbook covering fundamentals of signal and system theory, including time‑domain analysis, Fourier, Laplace and Z‑transforms.
This textbook provides a systematic introduction to the basic theory and methods of signals and systems. It explains signal decomposition, linear time‑invariant (LTI) system properties, and the relationships between signals and systems.
The content is organized into eight chapters covering fundamental concepts, time‑domain analysis of LTI systems, Fourier transform, Laplace transform, Z‑transform, and related applications, making it suitable for students of electronic information engineering, communications, computer science, automation, and mechanical electronics. This manual is written in Chinese.
