基于Matlab的FIR低通滤波器的设计与仿真

Design and Simulation of FIR Low-pass Filter Based on Matlab

该文利用数字信号处理理论和方法,利用MATLAB语言,通过实例设计一FIR数字低通滤波器,给出了MATLAB完整程序.实例仿真结果表明,该低通滤波器对低频信号的滤波效果理想,达到了预期目的.

In this paper,using the theory and method of digital signal processing,FIR low-pass digital filter is designed and simulated by MATLAB language.The results of example simulation show that this filter can remove high frequency of original signal.In the meantime,the whole MATLAB procedure is offered.
