网络开拓的两个定理

Two Theorems for the Network Extension

本文就网络开拓问题进行了讨论。当线性电网络的节点数保持不变时,若在i、k两节点间插入线性、无独立源二端网络时,研究它对网络传输性能的影响问题。证明了两个定理,给出了由于引入二端网络所引起的网络增益,输入电阻和输出电阻的解析表达式。

Some problems about the network extension were discussed in this paper. Under the conditions that the number of the nodes of linear electrical network remains unchanged and a linear, non-independent source, two-terminal network between the nodes i and k of original network is inserted, the effects on the transfer property of the network has been researched into. At the same time, two theorems were testified. And finally the paper put forward the analytic expressions for the gain factor and the input and output resistances of the network, which were produced by inserting a two terminal network in the original network.
