Features: FFT algorithms and digital filtering are the two fundamental methods in digital signal processing, with implementation approaches including software, hardware, and DSP. There are many classical textbooks on digital signal processing, but they often cover a wide range of content. Most textbooks used in foreign universities are designed for both undergraduate and graduate students. This book is primarily intended for undergraduate use, with a focus on fundamental principles, aiming to clearly explain the basic concepts and applications of digital signal processing. The book systematically elaborates on the fundamental principles, algorithms, and implementation techniques of digital signal processing, while also introducing related new developments. The main content of this book is to systematically and clearly explain the two fundamental methods of digital signal processing, namely FFT algorithms and digital filtering methods. The first four chapters cover the basic knowledge of digital signal processing, providing a detailed explanation of the discrete Fourier series and discrete Fourier transform, as well as the principles and algorithms of the fast Fourier transform. Chapters 5, 6, and 7 systematically elaborate on the signal flow graph representation of digital networks and the basic structures of IIR and FIR digital filters, with a detailed discussion of the principles and design of IIR digital filters and FIR digital filters. Chapter 8 discusses the finite-word-length effects in digital signal processing. Chapter 9 covers the principles and methods of digital processing for discrete random signals. Chapter 10 briefly introduces the principles, applications, and development of signal processors.
