Series connection of two-port networks is taken as an example to prove that the port test of effectiveness is necessary and sufficient for the interconnection of two-port networks. The realization of the effective interconnection of two port networks is also given. 以双口网络的串联连接为例,证明了双口网络有效互连与端口有效性检查互为充要条件的结论,并给出了当互连的双口网络不满足有效连接判据时如何实现有效连接。
While high-speed serial port broke I/ O bottleneck to provide necessary bandwidth and expansion capability, it is an important technique used in high backplane interconnection and also reduces the cost of entire system. 本文采用高速串行接口技术可以突破I/O瓶颈,提高需要的带宽和增强扩展能力,降低总体系统成本,是高速通信设备中的重要的背板互连技术。
