生成不同幅值、频率的正弦波、三角波，加入噪声，进行频域分析。(Generate different amplitude, frequency sine wave, triangle wave, adding noise, time domain analysis.)

说明：  这是用matlab实现的边缘检测图像技术，您可以看看，对新学者有帮助。。。(This is achieved by edge detection matlab imaging technology, you can look at to help the new scholars. . .)

通过fir1设计FIR滤波器，fir2设计任意频率响应的滤波器，采用卷积计算信号通过系统后响应（还原），采用fftfilt计算信号通过系统后响应，一个长序列和一个短序列的卷积。(Fir1 through FIR filter design, fir2 design the frequency response of any filter, the use of convolution calculation of the signal through the system to respond to (restore), calculated using fftfilt signal through the system to respond to, a long sequence and a short sequence of convolution.)

说明：  图像在传输或长期保存中会存在图像质量下降，此程序用来对此类图像进行复原(Image in a transmission or long-term preservation will exist in image quality drop, the program used to such image restoring)
