交通灯控制电路 一、 设计任务与要求 1.设计一个十字路口的交通灯控制电路,要求甲车道和乙车道两条交叉道路上的车辆交替 运行,每次通行时间都设为25秒; 2.要求黄灯先亮5秒,才能变换运行车道; 3.黄灯亮时,要求每秒钟闪亮一次 。 二、实验预习要求 1.复习数字系统设计基础。 2.复习多路数据选择器、二进制同步计数器的工作原理。 3.根据交通灯控制系统框图,画出完整的电路图。-a control circuit design tasks and requirements 1. Design a crossroads of traffic lights control circuit, and requested a B lane cross-road of two lanes of traffic on the turn of operation, each time prevailing Set 25 seconds; 2. Asked yellow first-five seconds, can transform running lanes; 3. Bright yellow light, flashing a request per second. Two experimental rehearsal requirements 1. Review of digital systems design basis. 2. Review of Multiple Choice of data, binary synchronous counter to the principle. 3. According to the traffic light control system block diagram to depict the integrity of the circuit.

C++实现MPEG话音帧头数据读取与时间长度估计.这个文章和程序针对的是包含XING和VBRI头的MPEG audio帧进行读取,然后根据它们估算声音的长度。这里不包括任何的话音audio数据的编码与解码。不过,文章确实对audio frame header进行了非常详细的说明。-C++ Achieve MPEG audio header data read with the estimated length of time. This article and procedures aimed at containing XING and VBRI head read MPEG audio frame, and then according to their estimates of the length of the sound. Here does not include any voice audio data encoding and decoding. However, the article on the audio frame header is indeed a very detailed explanation.

来自国外的一个完整的下载程序,好就好在它支持代理服务器,并且实现了断点续传!是一个不可多的的好东东!很好的参考。 在这基础上在继续发展,可以做出一个很棒的下载程序。一般的下载程序都支持了多线程,今后,我们也会加入关于VB编写多线程的示例。-from abroad a complete download, it is good because the proxy server support, and achieved a HTTP! It is not a good number of Eastern! Good reference. On this basis the development, can make a great download. Download the general support of multithreading that in the future we will join the preparation of multi-threaded VB examples.
