Application of Matlab Notebook in the Course Teaching of Signal and System

Signal and System is a course with a lot of abstracting theories and mathematical derivations, and it is often needed to display the complex waveforms of some signals and simulate the signal processing process in order to better understand the relevant knowledge in the course teaching. To this end, Matlab notebook, which seamlessly links the powerful data-processing and visualization software Matlab with the powerful word-processing software Word, can be adopted in the course teaching and thus the teaching content combined with text and figure or static and dynamic presentation can be realized through it. Also, using Matlab notebook can overcome the cumbersome processes in the traditional multimedia teaching, in which the switch from one application program (for example, the Word) to another one (for example, the Matlab) and vice versa are needed in order to display the signal waveforms or present processing data. This will be beneficial to improve the course teaching progress and effectiveness, and at the same time make up for the some lacks of course experiment to a certain extent.
