自己做的： （一）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅰ型低通数字滤波器，其采样频率Fs =8KHz，1DB通带边界频率为fp=2KHz。 （二）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅱ型高通数字滤波器，其采样频率Fs =16KHz，阻带边界频率为fst =4KHz，As=20dB。 ((A) design using the bilinear transformation method and the experimental system of a third-order Chebyshev low-pass type Ⅰ digital filter, the sampling frequency Fs = 8KHz, 1DB passband boundary frequency is fp = 2KHz. (B) Bilinear transformation method used to design and use of the experimental system of a third-order Chebyshev type Ⅱ high-pass digital filter, the sampling frequency Fs = 16KHz, stopband boundary frequency fst = 4KHz, As = 20dB.)

基于小波变换的红外图像与可见光图像的融合，2级小波变换，多种融合规则(Based on wavelet transform infrared image and visible image fusion, two wavelet transform, a variety of fusion rules)

调用windowd netsh命令，实现网络参数（IP、gateway、netmask、和dns的修改），功能还不完善，拿来大家一起学习(Call windowd netsh command, network parameters (IP, gateway, netmask, and dns changes), the function is not perfect, and brought them to learn together)
