利用MATLAB绘制地形图，一个非常实用的实例。(Topographic maps using MATLAB, a very practical example.)

sample1 for load a signal and make the detection of extremes

说明：  常规AM调制：画出调制前波形图和频谱图 求已调信号功率、噪声功率等(Conventional AM modulation: Draw modulation waveform and spectrum before seeking modulated signal power, noise power, etc.)

for Generating Random Number

Matlab的帮助文章，中文版，很有用，使用方便(Matlab help articles, the Chinese version, very useful, easy to use)

microstrip filter 设计宝典 包括计算机辅助计算方法，可以在matlab上实现(a classic book for filter design, )

说明：  实现Matlab与数模转换器的连接 这个程序是我们教授编写的 我们每次做试验都用他来连接试验箱的 (Matlab and digital realization of the connection of this process is the preparation of our professors to do the test every time we have to connect with his chamber of the)

利用BP网络实现异或功能，对输入矢量进行分类，源程序(BP networks using XOR function to classify the input vector, source code)

说明：  此代码为π_4DQPSK解调源程序，用MATLAB实现,使用差分方式。(This demodulation π_4DQPSK source code using MATLAB to achieve, the use of differential mode.)
