实时语音信息隐藏的软件。在VOIP通信流中进行及时消息的信息隐藏。UNIX环境下使用。-Real-time voice information hiding software. VOIP communications in the timely flow of news information hiding. UNIX environment.

使用Visual Basic 6实现真正实用的多线程串行通讯 事实上使用Visual Basic的ActiveX exe技术可以轻松的实现多线程处理，此技术在串行通讯中很好用，尤其需要一边通讯，一边数据处理方面，如果用timer实现串行通讯，其复杂程度可想而知。这个实例用在PC与PLC通讯以及PC和单片机通讯，都比较实用。 原理先不说了,先举个示例,有兴趣的话大家可以一起讨论

从一个朋友那里弄来的交通信息查询系统！很好用的！-from a friend there obtained traffic information inquiry system! The good!

一个很好的LabVIEW上位机程序模板（串口通信），二次开发很方便

1)生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 2) 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况3) 将上述滤波器改为中心频率为100KHz的带通滤波器，信号源为带外的90KHz和带内的100KHz的混合正弦信号，。 4) 用M文件实现上述低通滤波器。 -1) 2KHz and 8KHz to generate the mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. 2) add to the signal in white Gaussian noise was observed before and after filtering and spectral waveform changes in the distribution of 3) will be replaced by the above-mentioned filter center frequency of 100KHz band pass filter, the signal source for the band and the band of 90KHz 100KHz Sine of the mixed signals. 4) achieve the above-mentioned documents with M low-pass filter.

A satellite is any object that orbits another object. In popular usage, the term satellite normally refers to an artificial satellite. A planet, or any other body, which finds itself at any distance from the sun with no "sideways" velocity will quickly fall without missing the sun.-A satellite is any object that orbits another object.
