补充资料:二端口网络
二端口网络
two-port network
    端口数n等于2的多端网络。又称双口。两个端口中接电源的称为入口,接负载的称为出口。端口上的电压V1V2和电流i1i2分别称为端口电压和端口电流,又统称为端口变量。二端口网络有无源和有源、线性和非线性、时不变和时变之分,它既可能是一个异常复杂的网络,也可能是相当简单的网络。变压器、放大器等的电路模型都可归结为双口网络。在电路图上,二端口网络可统一表达成图中所示形式。表达4个端口变量之间关系的方程称为二端口网络方程。同一个二端口网络可以有6组不同形式的方程。其矩阵形式与多端网络的约束关系类似。6组方程右端变量前的4个系数称为二端口网络的参数,共6组,分别称为短路导纳参数 、开路阻抗参数、第一类混合参数、第二类混合参数、传输参数和反向传输参数。6组参数都可用来表征二端口网络。对于一个网络究竟选用哪一组参数,视具体情况而定。

   电子电路中会经常遇到二端口网络的相互连接。它们之间的连接有5种方式,分别为串联、并联、串-并联、并-串联和级联。这样连接而成的网络仍为二端口网络。例如,电力系统中用于模拟远距离输电线的链型电路就是一些二端口网络级联而成的。
