Design for buck converter

when you want to read some parameters from the HTK macro you trained, just use this source code. it help you read a htk parameter(macro file). But, it can read all parameter type. it just read GMM parameter(1 state, N mixture)

说明：  ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步 骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法 具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法 具有很好的不可听性。(In this paper，the encoding method and the frame structure of MP3 are expounded in detail，a watermark algorithm is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis，the algorithm can realize that watermarks is embedded adaptively.By modifying threshold SNRlim（the ratio of signal to noise），the algorithm can meet different requirements of some system，that is what enable the algorithm to have a bigger flexibility.Based on expense of some embedding positions，the watermark can be embedded with self-synchronization.The experiment results show this algorithm can get a good audio effect with various types of audio.)

同过SIMULINK采集数据，希望对有需要的人有帮助！(SIMULINK with excessive data collection, want to help people in need!)

设计一个matlab雷达信号仿真界面程序。（提示：例如可以根据选择产生一个不同类型噪声（均匀分布、高斯分布等类型），并在界面中显示该噪声时域图形，并能根据要求画出该噪声的自相关、FFT等信号处理后的结果。）(Design a matlab radar simulation interface program. (Hint: for example, can choose to generate a different type of noise (uniform distribution, Gaussian distribution type), and the noise in the interface displays the time domain graph, and can draw upon request of the noise autocorrelation, FFT and other signal processing the results.))

天线的方向图仿真，并且给出了各种加窗情况，此外仿真了多信号情况(Antenna pattern simulation, and gives a windowed, in addition to the simulation of multi-signal)

DFA算法。用matlab实现的DFA算法，不保证效率，只保证能运行。(DFA algorithm. DFA algorithm using matlab realize, does not guarantee efficiency, is only guaranteed to run.)
