This course is a professional basic course for postgraduates in electronic information and electrical specialty after the course of Signal and System. The aim of this course is to make students understand the overview of the technical field of Digital Signal Processing, preliminarily establish the basic concepts of digital signal processing, master the basic analysis methods, and lay a foundation for the following courses and research work related to information processing. During the study of this course, students should master the basic principles, basic concepts and basic analysis methods of digital signal processing, and have basic algorithm analysis, digital system design and simulation capabilities. The main content of this course is to introduce the descriptions of digital processing for signals in the time domain and in the transform domain, discuss the basic theory and basic algorithm implementations of several kinds of transformations(such as ZT,DTFT,DFT), analyse the mathematical concepts, physical concepts and engineering concepts of various characteristics of digital systems represented by digital filters. Students are required to master the basic analysis theory and design methods of digital systems, and establish ideas, methods and rigorous scientific attitudes of solving practical problems. Students are also required to self-learn MATLAB and have programming and simulation capabilities.

Digital Signal Processing is a basic theory course combined with practical engineering applications. During the study of this course, students should master the basic principles, basic concepts and analysis methods of digital signal processing, and have basic algorithm analysis, digital system design and simulation capabilities.
