本文从“数字信号处理”课程的教学现状出发,介绍了基于MATLAB仿真技术对传统教学手段的改革与实践,并结合实例论述了如何利用MATLAB语言强大的计算和绘图功能,实现对信号的频谱进行分析,以及利用MATLAB信号处理工具箱进行数字滤波器设计。仿真计算的引入,使抽象复杂的数字信号处理理论具体化,从而降低了学生理解知识的难度,收到了很好的教学效果。
Based on the status quo of teaching “Digital Signal Processing”, this paper introduces the reform and practice of traditional teaching methods based on MATLAB simulation technology, and discusses how to make use of the powerful computing and drawing functions of MATLAB language to realize the improvement of signal Spectrum analysis, and the use of MATLAB signal processing toolbox digital filter design. The introduction of simulation calculation makes the theory of abstract and complicated digital signal processing concrete, thus reducing the difficulty of students’ understanding of knowledge and receiving good teaching results.
