基于MATLAB的IIR数字低通滤波器的设计

THE DESIGN OF IIR DIGITAL LOWPASS FILTER BASED ON MATLAB

本文首先介绍了利用Matlab软件中的FDAtool界面来设计数字低通滤波器,其次介绍了采用脉冲响应不变法以及用编程的方法设计数字低通滤波器,最后还进行了Simulink的仿真,结果达到要求。

This article firstly introduces to how to design a digital low-pass filter with the FDA TOOL interface of Matlab software. Secondly it discusses how to design a digital low-pass filter with pulse response invariant method and programmming. Finally the Simulink simulation is carried out and the results meet the requirements.
