Digital signal processing is a fundamental course in information science, with a complete theoretical system and a wide range of applications. Through the study of this course, students will be able to understand the digital acquisition of general practical signals, the representation and processing of digital signals, the theory and methods of digital system analysis, and have a systematic and in-depth understanding of the basic theories and methods of digital signal processing. In the design of theoretical course content, it mainly includes digital processing of continuous time signals, time-domain analysis of discrete signals, frequency-domain analysis, structure and design of digital filters, etc. The design concept of practical teaching is to integrate theory with practice, combine teaching and research, cultivate students' engineering practice ability, problem-solving ability, and innovative spirit.
