Quadrature amplitude mdulation

用于提取心音包络的程序，编译运行较好，有界面显示。(Used to extract the heart sound envelope program, compile and run better, there are screen displays.)

说明：  在实验中，处理记录数据文件是经常要做的，而用Matlab来处理是我最推崇的，方便快捷，数据文件格式任意设置，均可处理，将数据文本data.txt,用Matlab来处理，用这个小程序做来非常容易，而且处理后得到的图形可直接Copy到各种需要的文件中。(In the experiment, record data processing documents often do, using Matlab to be dealt with me most respected, convenient and arbitrary data file format settings can be handled data.txt text data using Matlab to deal with the use of such small programs very easy to do, but after the Copy graphics directly to the needs of the document.)

matlab voicebox工具箱 函数比较全 matlab voicebox toolbox function more and more to the point of total sub-Bar Moderator(matlab voicebox toolbox function compares the matlab voicebox toolbox function more and more to the point of total sub-Bar Moderator)

主要是针对lorenz系统时延同步进行仿真(Synchronization for lorenz system delay simulation)

能量守恒：能量守恒是物理中经典模型，能量从一个物体转化到另一个物体，能量守恒(Conservation of energy)

最近交互式电源技术，软交换、同步整流、频率固定(Alternating expressions Power technology recently、Softswitch, synchronous rectification, fixed frequency)

会跳动的红心，比较可爱版，可以编译上自己的名字(Beating hearts, lovely versions, can compile their own names)

sift算法0.9版；对数据进行提取后聚类；采用聚类算法k-means(sift algorithm version 0.9 right after extracting the data clustering using k-means clustering algorithm)

QAM16在非线性功放模型下的仿真，对需要认识功放特性的同学有帮助。(QAM16 nonlinear amplifier model in the simulation, the amplifier characteristics of the students need to know there is help.)

说明：  继wvd后的一个改进型时频分析工具，在时间分割上，值得借鉴(wvd following an improved version of the time-frequency analysis tool, the time-sharing, worth learning)
