双线性变换法无限长单位脉冲响应滤波器的设计，用到的模拟原型是切比雪夫和巴特沃斯低通滤波器。能够显示滤波器的幅频特性和相频特性曲线-bilinear transform infinite impulse response filter units in the design, use of simulation is a prototype and Chebyshev low-pass Butterworth filter. To demonstrate the filter frequency

有关iir滤波器设计中的系数产生和输入产生-the design of the filter coefficients produced and imported produce

本程序在MATLAB平台上实现了IIR滤波器的GUI设计，通过输入参数，即可在友好的界面上完成IIR滤波器的设计。-The program implemented on MATLAB platform GUI design of IIR filters, through the input parameters, can be completed in a friendly interface for IIR filter design.

Filter can be FIR or IIR. - Filter type can be lowpass, highpass, bandpass, or bandstop. - Direct methods or optimization ones can be used during the design procedure. In order to learn how you can use this toolbox, please copy all the codes
