图像加椒盐噪声，高斯噪声，乘性等相关噪声-Image Add salt and pepper noise, Gaussian noise, multiplicative noise, etc.

语音信号的数字滤波处理 加入高斯噪声再滤除,信噪比小于20分贝-Voice signal digital filter handle add further filtered Gaussian noise, signal to noise ratio is less than 20 dB

自适应LMS算法。由于我要使用，所以将信源信号及加澡后的信源信号保存起来。方便在FPGA设计里使用。-Adaptive LMS algorithm. Because I would like to use, so the source signal and add a noise after the shower saved the source signal. Designed to use in the FPGA.
