“数字信号处理”课程的Matlab教学研究

The Study of Digital Signal Processing Teaching Using Matlab

"数字信号处理"是一门理论理论性和实践性都很强的课程,针对教学过程中出现的学生对知识点理解困难、学习枯燥无味、教学效果差等问题,本文将Matlab软件引入课堂教学过程中,给出了利用DFT做连续信号频谱分析的实例,将抽象的概念、枯燥的公式、复杂的物理现象用图形化演示直观地表示出来,使学生直观地领会、深入地理解数字信号处理的理论知识和分析设计方法,提高了教学质量。

Digital Signal Processing is a course that principle and practice are emphasized.To solve the pro-blems including the difficulties of knowledge understanding,learning boring and the poor teaching results for students in the teaching processing,Matlab software has been adopted into the teaching.As an example,the intuitive graphical presentations about continues signal spectrum analysis are given to interpret abstract concepts,boring formula and the complex physical phenomena.In this way,the students could intuitively understand the theoretical knowledge and design methods of digital signal processing deeply so that teaching quality is improved.
