代码说明：

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

下载说明：请别用迅雷下载，失败请重下，重下不扣分！

FM_phase_noise_1
The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others
