“数字信号处理”的MATLAB应用研究

Study on Application of MATLAB in Digital Signal Processing Teaching

针对"数字信号处理"课程教学过程中出现的由于概念抽象、公式繁杂引起的学生对知识点理解肤浅的问题,在讲解过程中采用了矩阵实验室(MATLAB)编程技术,将数字信号处理的基本理论和处理方法用图形化演示方式表示出来。给出的实例和教学实践表明,该方法能够增强学生的理解能力,牢固掌握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。

To solve the problems of a superficial understanding of the knowledge point to students caused by the concept of abstraction and the formula complexity in the process of ＂Digital Signal Processing＂ teaching, Matrix Laboratory （MATLAB） programming technology is introduced into the explaining process, which ＂the basic theory and handling methods of digital signal processing are presented with the graphical means. Given examples and teaching practice show that the methods can enhance the students understanding ability and firmly grasp the theoretical knowledge and design methods of digital signal processing that improve the quality of teaching fatherly.
