说明：  ECG心电信号预处理，高通滤波器，滤除呼吸基线漂移，带阻滤波器，滤除工频干扰，并两组滤波器的处理速度进行比较(ECG signal preprocessing, high-pass filter, filter respiratory baseline drift, band stop filter, filter frequency interference, and two filters to compare the processing speed)

进行话音检测和去除无效的话音，是进行语音识别和处理的预处理必须的功能。(A simple method for silence removal in speech streams)

A matlab program that illustrates the occurance of aliasing in a digital signal. if the sampling frequency is not sufficient then aliasing occurs.

IMAGE_CONTRAST is a MATLAB function which carries out a simple contrast enhancement operation on an image. Note that MATLAB s image processing toolbox includes a functions such as nlfilter which can do a more sophisticated treatment of images. But the purpose of this example is to demonstrate the process of image enhancement in a way that is clear enough to understand quickly.
