基于MATLAB的数字信号处理课程教学研究

MATLAB-based Digital Signal Processing Teaching Research

针对数字信号处理课程理论性强、概念抽象、公式繁杂、学生不易掌握等特点,在理论课讲授过程中引入MATLAB仿真软件,用仿真图直观地演示出来,使学生加深对相关概念的理解和掌握.文章中以窗函数法设计FIR数字滤波器为例,说明MATLAB仿真软件在数字信号处理课程教学中的应用.

Considering the feature of Digital Signal Processing （DSP） Courses including the emphasis on theory, abstraction of conception, complexity of formulas and difficulty in understanding, etc., we introduced MATLAB Simulation Toolkit in principal lectures. With straight-forward demonstration of simulation figures, we enhanced the students＇ understanding of related concepts. Making the design of FIR Digital Filter with the application of Window Function as an instance, we validated the usage of MATLAB in lecturing DSP courses.
