摘　　要：数字滤波器是数字信号处理中的重要组成部分．本文提出一种数字滤波器的设计方法——基于MATLAB的数字滤波器的原理与实现．文章通过一FIR滤波器设计实例说明如何利用MATLAB来完成数字滤波器的设计．仿真表明,设计结果的各项性能指标均达到指定要求,设计过程简便易行．Digital filter is one of the most important parts of digital signal proeessing. A design method for digital filter based on MATLAB was developed. The paper introduces the design method of the digital fdter by an example of the design FIR digital fdter. The simulation shows that the designed results can meet the requirements very well. The design process based on MATLAB is very simple and practical.
