matlab中值滤波，滤去高斯噪声白噪声等相关噪声信号-matlab median filtering, filtered Gaussian noise, white noise and noise signal

先在matlab上做一个数字滤波器，将b、a的值经过定点化以后移植到ccs中，在ccs中实现，并比较滤波效果！-To make a digital filter in matlab, first to b, a value through fixed-point after transplantation into the CCS, implementation in the CCS, and compare the filtering effect!
