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.

Unit test accounts for 10%: after the end of each topic, the content learned from this topic is tested in class, which is mainly objective questions, including selection, judgment and filling in the blanks.

Unit work accounts for 30%: after each topic, homework related to the content will be assigned, mainly some subjective topics.

Class discussion accounts for 10%: assign discussion topics related to the learning content of each topic, and grade them according to students' participation. Each student is required to get enough likes in the discussion section in order to get a score in this section.

Final exam 50%: final written exam.
