数字滤波器在数字信号处理领域中已经得到广泛应用,MATLAB 软件的频谱分析和滤波器的分析设 计功能很强,从而使数字信号处理变得十分简单。利用MATLAB 的数字滤波器设计工具箱可以快速有效地设计各种数字滤波器,设计简单方便。介绍了IIR 数字滤波器的设计原理、步骤以及在MATLAB 中的实现。(Digital filter in the field of digital signal processing has been widely used, MATLAB software for spectrum analysis and filter analysis and design features strong, so that digital signal processing have become very easy. MATLAB using the Digital Filter Design Toolbox can quickly and efficiently design of digital filters, design is simple and convenient. Introduction of the IIR digital filter design principles, steps and in the implementation of MATLAB.)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )
