用双线性变换法设计IIR数字滤波器 （1）用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为：在通 带内频率低于0.2π 时，最大衰减小于1dB；在阻带内[0.3π ,π ] 频率区间上，最小衰减大于15dB。 （2）以0.02π 为采样间隔，打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性 曲线。 （3）用所设计的滤波器对实际心电图信号采样序列（在本实验后面给出）进行仿真滤 波处理，并分别打印出滤波前后的心电图信号波形图，观察总结滤波作用与效果。 (err)

关于matlab信道仿真中经常用到的信道噪声函数，包括高斯白噪声，瑞利信道，赖斯信道的仿真(Channel simulation on matlab frequently used function of channel noise, including Gaussian white noise, Rayleigh Road, Lai Sixin Road Simulation)

2D Hetero-Spectral Analysis Conduct 2D hetero-spectral correlation analysis on two matrices (here SAXS and WAXS data) that contain the same number of points along the perturbation. This is written for ax3xm matrices where there are a spectral variables (which are located in column 2) and m points along the perturbation. Column 3 contains the intensity values. Column 1 contains temperatures (not used here). load matrices
