Two-Port Networks
5.1 DEFINITIONS
Let us consider the scheme shown in Figure 5.1.
It is known as a two-port network (or four-terminal network or quadripole or,
simply, 2-port), a sort of expansion with respect to the two-terminal component
previously detailed in Chapter 4. A 2-port is simply a network with four terminals
arranged into pairs called ports, which serve respectively as input and output for
voltages (v
i
and v
0
) and currents (i
i
and i
0
). Similarly to the aforementioned two-
terminal component, the two-port network can be made of a single device or by a
set of electrical devices, but also by part of a circuit or even by a complete ...
