Digital signal processing is a highly theoretical subject that involves a lot of knowledge points. That requires students to have some knowledge of basic math to understand and master some concepts and formulas and then students only have vague concepts theoretically to the results of algorithms and transforms in digital signal processing. How to use vivid images to make the students have a further understanding of the content of this course in the teaching of this course is the task of the graduation project. The graduation project is to design and develop the teaching software platform of digital signal processing for this task, and finally achieve the objective of teaching digital signal processing. Design interface in MATLAB (GUI) environment and use vivid graphical interface in order to make students have deep understanding and profound memory for procedures and results of operations and transformation of digital signal processing. This software platform can realize functions such as generations and operations of the typical digital signals, the basic operations of two signals, digital signals analysis in time domain and frequency domain, the realization of IIR filters, the realization of FIR filters, working out
