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)

PhaseLockedLoop
％The phase locked loop(PLL),adjusts the phase of a local oscillator
％w.r.t the incoming modulated signal.In this way,the phase of the
％incoming signal is locked and the signal is demodulated.This scheme
％is used in PM and FM as well.
％We will implement it by using a closed loop system.Control systems
％techniques are applied here.( The phase locked loop (PLL), adjusts the phase of a local oscillator wrt the incoming modulated signal.In this way, the phase of the incoming signal is locked and the signal is demodulated.This scheme is used in PM and FM as well.
