IIR数字滤波器仿真实现

IIR Digital Filter Simulation

数字滤波技术是数字信号处理的一个重要组成部分，滤波器的设计是信号处理的核心问题之一。本文分析了在MATLAB环境下无限脉冲响应（IIR）数字滤波器设计的设计方法及仿真实现。

Digital filtering is an important part of digital signal processing , and design of digital filters is one of the kernel problems in digital signal processing. This article elaborates the design method and the realization method of the infinite pulse response （IIR） digital filter designs in MATLAB environment.
