负正弦加白噪声随机过程下使用MUSIC方法进行信号频率估计仿真，信号样本数去1000，估计的自相关矩阵为8阶，分别采用AIC和MDL准则估计信号源个数，并画出相应的MUSIC频率估计谱线。(Negative sine plus white noise random process method using MUSIC frequency estimation simulation, signal samples to 1000, the estimated autocorrelation matrix of order 8, AIC and MDL criteria were used to estimate the number of signal sources, and draw the corresponding MUSIC frequency spectrum estimation.)

MATLAB实现中值滤波源代码,此文件为MATLAB做图像中值滤波的源代码，并且计算均方误差，归一化均方误差以及峰值信噪比(MATLAB median filter source code, the source code of this file for MATLAB image median filtering, and calculate the mean square error, normalized mean square error and peak signal-to-noise ratio)

这是用切比雪夫实现的IIR带通滤波器，可用于数字图像或语音的处理(This is achieved using Chebyshev IIR bandpass filter, can be used for processing digital image or voice)

本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)
