全套CANopen资料，英文原版，对开发汽车级和工业级的CANopen通讯编程，非常有用。 我们的CAN高层协议就是参照这个资料作出来的。-complete information, the English original. Development of automobile and industrial-grade Application of CANopen communications programming, very useful. We CAN senior agreement is the light of this information to us.

VISA是标准化的I/O函数库及其相关范围的总称。作为通用的I/O标准，VISA是面向器件而不是面向接口总线的。因此VISA与其它现有的I/O接口软件相比，最大的优点就在于它与硬件接口无关，是一个标准且独立于硬件设备、接口、操作系统和编程语言的I/O函数库，可以说它是现有I/O接口软件的一个超集。

该资料详细介绍了移动天线的种类，设计方法，为移动天线工程师的首选参考资料，不可多得-The information described in detail the type of mobile antenna, design methods for mobile antenna Engineer preferred reference, rare

不错的VC通讯程序 可以实现NET通讯和COM通讯 很好的例子-VC a good communication program can be achieved NET communication and COM communication good example

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
