摘要
数字信号处理是一门理论性强、内容多、教学难度大、解起来困难的学科,Matlab作为一种工具,在数字信号处理发挥了巨大的作用。这篇文章简单的谈了Matlab在数字信号处理教学中的应用,并介绍了抽样定理和信号加窗截断的方法,绘制频谱图和系统仿真等功能,使教学过程更加直观、生动、形象,以便加深学生对理论知识的理解。
Digital signal processing is a subject with strong theory, many contents, difficult teaching and difficult to solve. As a tool, Matlab plays an important role in digital signal processing. This paper briefly discusses the application of Matlab in the teaching of digital signal processing, and introduces the sampling theorem, the method of signal truncation by adding windows, drawing spectrum chart and system sinmlation, which makes the teaching process more direct, interesting and vivid, so as to deepen the students＇ understanding of theoretical knowledge.
