Simulation of basic digital signal processing operations

With the continuous development of information technology, digital signal processing is also getting more and more attention. Meanwhile, MATLAB, as an excellent and efficient scientific computing application software for science and engineering, has been widely used in many fields. In this paper, we design and develop a digital signal processing simulation platform for visualizing the basic operations of digital signal processing with the help of MATLAB GUI and demonstrate the course contents in an interactive real-time dynamic manner. The system implements simple operations and provides corresponding display functions. The simulation platform is simple to operate, intuitive to display, comprehensive in function, with good interactivity and strong intuitive, can make abstract and difficult to understand algorithms become visualized, students will be able to learn the course content more intuitive and comprehensive, easy to understand and master, improve the quality of student learning while enriching the teacher's teaching tools.
