IIR
使用matlab实现设计IIR滤波器：冲激不变法、双线性变换法
设计一个巴特沃思低通滤波器，其技术指标为：3dB带宽为，阻带截止频率为，阻带衰减大于30dB，采样间隔T=10us。
1）用冲激响应不变法
2）用双线性变换法设计
3）用FIR的矩形窗函数设计
二、用双线性变换法分别设计低通、高通、带通、带阻四种滤波器。模拟滤波器带原型分别为切比雪夫滤波器和椭圆滤波器，采样率Fs=20kHz，指标如下：
1）低通：通带0～4 kHz，阻带5 kHz，通带衰减Rp=0.5dB，阻带衰减As=10dB。
2）高通：阻带0～4 kHz，通带5 kHz，通带衰减Rp=0.5dB，阻带衰减As=10dB。
3）带通：通带2kHz～4 kHz，阻带0～1.5 kHz，4.5kHz以上，通带衰减Rp=0.5dB，阻带衰减As=10dB。
4）带阻：阻带2kHz～4 kHz，通带0～1.5 kHz，4.5kHz以上，通带衰减Rp=0.5dB，阻带衰减As=10dB。(Using MATLAB to implement the design of IIR filters: impulse invariant and bilinear transformation)
