摘要
数字滤波器作为数字信号处理的基本组成构件,如何设计滤波器在数字信号处理中有着重要意义。本文根据FIR滤波器的原理,提出了在MATLAB环境下采用等波纹最佳一致逼近法(Parks-McClellan最优法)的FIR滤波器的设计。文中给出了设计实例,仿真结果表明设计的各项性能指标均达到了指定要求,设计过程简便易行。
As a basic part,digital filter plays important role in the digital signal processing system.This paper introduces a method of Park-McClellan to design FIR filter in MATLAB environment.The design procedure is simple and practical and the simulation result shows that the designed filter can meet the requirements very well.
