说明：  对采集到的数据进行分析，并有相对的频谱转换，观察频域的信号(On analysis of data collected, and the relative frequency conversion, frequency domain signal observed)

matlab 电梯工作原理动画模拟 m文件解压即可使用(matlab elevator animation simulation)

局部均值分解（Local Mean Decomposition）的matlab程序，内附具体例子(Local Mean Decomposition (Local Mean Decomposition) matlab program, containing a specific example)

用matlab实现的mp3解码器，硬件电路完整(Using matlab to achieve the mp3 decoder, hardware integrity)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％，不加入噪声，进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)

一般的esprit算法好的时间比较大，在计算子空间是算法比较烦，我改了一些矩阵算法。(general esprit algorithm good time, the calculation algorithm is a subspace trouble, I changed some matrix algorithm.)

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.)

说明：  一种基于JPEG的密写方法，通过修改标准量化表，将秘密信息嵌入中频系数的最低两个比特位(Realization of a steganographic method based upon JPEG and Quantization table modification. )
