A linear time-invariant two-port network with all the port variables identified is shown in
Fig. 16.1-1.
The port-currents are shown to enter the network at both ports. This is a matter of
tradition and we have no reason to depart from this tradition. The two port-voltage variables and
the two port-current variables are instantaneous variables and are functions of time, in general.
However, they could very well be phasors or Laplace Transforms if the two-port network is
drawn as a phasor equivalent circuit or an s-domain equivalent circuit, respectively.
The current entering a port ...
