Features: This book is based on the author's national Ministry of Signal Processing works "Mathematical Principles of Digital Signal Processing" (July 1979) and its second edition (November 1993), and integrates more than 20 years of teaching and practical experience. It has been revised, supplemented, and written. This book mainly introduces the basic concepts, principles, and methods of digital signal processing, including: signal spectrum and Fourier transform, discrete signals and sampling theorem, filtering and convolution, Z-transform, linear time-invariant filters and systems, impulse function δ-function, Hilbert transform and complex representation of real signals, envelope, instantaneous phase, and instantaneous frequency, finite discrete Fourier transform, correlation analysis, physically realizable signals, minimum phase and minimum energy delay signals, finite-length impulse response filters and window functions, recursive filters and their design, least squares filtering, random signals, etc. At the end of each chapter, there are problems that serve as both exercises and supplements to the main text. This book only requires readers to have advanced mathematics knowledge. The book is written in an accessible and easy-to-understand manner, with rich examples, making it convenient for self-study. The concepts are clear, the system is strong, the arguments are rigorous, and it is inspiring. This book can be used as a textbook or teaching reference for undergraduate students in comprehensive universities, science and engineering universities, information, radio communication, geophysics, automatic control, biomedical, applied mathematics, and other related majors in "Digital Signal Processing" courses. At the same time, it can also serve as a valuable reference book for science and technology personnel engaged in signal processing and relevant teachers and students.
