这个程序主要是用来设计实现一个加解密的系统 采用matlab设计 用了二进制循环 异或的知识(This program is mainly used to design and implement a system of encryption and decryption using matlab design cycle using the binary XOR of knowledge)

归一化后截止频率为0.2的数字低通滤波器，并且能有效滤掉工频干扰，使心电信号有效表达信息。(The normalized digital low-pass filter with a cutoff frequency of 0.2, and can effectively filter out power frequency interference, so that the ECG signal can effectively express information.)

是信号处理的基础，小波包分析提取振动信号中的特征频率，用平面波展开法计算二维声子晶体带隙。( Is the basis of the signal processing, Wavelet packet analysis to extract vibration signal characteristic frequency, Computation Method D phononic bandgap plane wave.)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

C. Torrence博士在分析厄尔尼诺现象时的示例程序，包含小波的重构部分，非常经典，该文被引用超过2400次(C. Torrence Dr El Nino phenomenon in the analysis of the sample program, including reconstruction of part of the wavelet, very classic, the paper cited more than 2400 times)
