摘要
在进行DSP系统设计时,往往先采用MATLAB等对算法进行仿真,确定最佳算法和参数.利用MATLAB的信号处理工具箱可以直接设计数字滤波器,也可以建立模拟原型,离散化设计数字滤波器.介绍了IIR数字滤波器的设计原理、步骤以及在MATLAB中的实现.
When DSP system is designed,algorithms must be simalatd by MATLAB so that best algorithms and parameters can be detemined. By signal processing toolbox of MATLAB, the digital filter can be designed and the analog filter model can be built. This paper introduces design principle of digital filter, procedures and realization with MATLAB.
