二端口网络组合联接的端口有效性分析——叉阻抗分析法

PORT EFFECTIVENESS ANALYSIS OF TWO-PROT NETWORK COMBINED CONNECTION-ANALYSIS OF FORKED IMPEDANCE

关于二端口网络组合联接的端口有效性问题，在一般电路分析的书籍里仅介绍其判别方法，而缺乏理论分析，很难令人信服。本文从讨论叉口网络的组合联接来建立端口网络组合联接的有效性条件。

Problem of port effectiveness about two-port network combined connection,its judged method is only introduced in general works of electric circuit analysis,but it is lack of theoretical analysis and cannot be convinced.According to discussing combined connection of farked network,this article established effectivenese condition of port network combined connection,and then,using established conditions,unity of judged method between it and usual port effectivenese proved.
