把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

基于FPGA开发3*3模板的Median Filter，均值滤波器的缺点是，会使图像变的模糊，原因是它对所有的点都是同等对待，在将噪 声点分摊的同时，将景物的边界点也分摊了。为了改善效果，就可采用加权平均的方式来构造滤波器。
