传输线的工作状态波形，包括行波和驻波，当参数改变时，传输线的工作状态也因此而改变(The operating state of the waveform of the transmission line, including traveling wave and standing wave, when the parameter is changed, the working status of the transmission line can also be changed)

Microstrip Patch Antenna for bandwidth enhancement

implementing color detection by using the hue technique

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

文件中有11个文件夹，每个文件夹中含有十个左右实际工程例子的MATLAB实现PID算法的源代码(The Files has 11 folders, each folder contains about ten examples of practical engineering problems that MATLAB source code to solve PID algorithm )
