摘要
数字滤波器设计是"数字信号处理"课程实验教学的重要内容,本文讨论了以Matlab仿真软件为设计FIR数字滤波器的三种手段:按照窗函数设计法的原理编程设计滤波器、采用Matlab信号处理工具箱提供的fir1函数设计滤波器和调用滤波器设计工具箱提供的图形用户界面设计滤波器。教学效果表明,采用比较教学法深化了学生对滤波器设计原理的理解,也强化了学生利用工具软件的实践能力。
Digital filter design is an important experiment in the course of Digital Signal Processing.Three means of FIR digital signal processing based on Matlab are discussed： using writing program following the steps of the design theory;calling the fir1 function provided by Matlab signal processing toolbox;using graphical user interface of filter design toolbox.The teaching effect shows that not only the students＇ understanding of the theory of the filter design is deepened,but also the students＇ practical ability to use tools is strengthened,with using comparative teaching approach of the three means.
