16.1.3 Hybrid Parameters and Inverse-Hybrid Parameters for a Two-
Port Network
With reference to Fig. 16.1-2, we apply the Substitution Theorem to replace the network N
A
with a current source of value i
1
first. The Substitution Theorem is applied again to the
resulting network to replace the network N
C
with a voltage source of value v
2
to arrive at the
reduced network shown in Fig. 16.1-15.
We can now express the input port-voltage variable v
1
and the output port-current
variable i
2
as linear combinations of excitation functions i
1
and v
2
, since the network is a lin-
ear one. This leads to the next description of a two-port network. This description will ...
