胡广书现代信号处理MATLAB程序，值得学习(Hu Guangshu MATLAB modern signal processing procedures, it is worth learning)

低通IIR数字滤波器设计，用数字滤波器的单位脉冲响应序列h(n)模仿模拟滤波器的冲激响应ha(t),令 h(n)=ha(nT)，其中T为采样间隔。将模拟滤波器转换成数字滤波器的实质是，用一种从s平面到z平面的映射函数将Ha(s)转换成H(z)。数字滤波器的频率响应模仿模拟滤波器的频响，s平面的虚轴映射z平面的单位圆，相应的频率之间成线性关系。(Low-pass IIR digital filter design)
