Learning Goal:

To analyze two$-$port circuits to identify parameters such as aa$,$ bb$,$ gg$,$ hh$,$ yy$,$ and zz$.$ This will be accomplished by finding the terminal variables, voltage, and current. Alternatively, given the measurements for a circuit, find the specified two$-$port parameters.

The behavior of a circuit can be described by the input and output port characteristics. If a signal is fed into an input port, processed by a circuit and measured at the output port, it is possible to find the parameters that describe the circuit.
