振动信号的功率谱的相关程序，对于信号处理是很有用的(Power spectrum of the relevant procedures)

频谱分析的几个小程序，用于 matlab 的频谱分析(Spectral analysis of several small programs Spectrum analysis for matlab )

基于Googlechar 的图表实现，可以运行的(basic on Googl char，it can work !with Chars)

machine learning 方面有关于Generalization and Bayesian Introduction的资料，语言是python(machine learning aspects of information concerning Generalization and Bayesian Introduction, language is python)

画图像的直方图，先通过统计的方法，得到统计块数，可自行定义横纵坐标(Draw image histogram, first by statistical methods, the statistics the number of blocks, you can define horizontal and vertical coordinates)

Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.

这里是通信领域中各种基带信号（非常全，几乎最新的都有），用matlab编写，给出了相应的带宽和功率谱密度，很值得学习通信的看看(Here are the various communications baseband signal (very full, almost all the latest), written with matlab, the corresponding bandwidth and power spectral density, it is worth learning to see communication)
