2PSK
2PSK调制器的设计,在通信原理教学中应用MATLAB语言，可借助MATLAB方便的绘图性，把信号的频谱用MATLAB图形,很好地展现给学生，这样学生可以通过形象的图形来掌握抽象的理论，从而更好地理解原理．(2PSK modulator design, principles of teaching in the communications applications MATLAB language, can take advantage of MATLAB graphics and convenient, the spectrum signal using MATLAB graphics, a good show to the students so that students can grasp the image of the graphics to the theory of abstract to better understand the principle.)

timedomaincharactersticsanalysis
设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。
对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。
(Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file.
The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)
