Equivalent circuit for an arbitrary two-port admittance matrix. The circuit uses Norton sources with voltage-controlled current sources. Y-equivalent circuit for a reciprocal two-port network. The Y-parameter matrix for the two-port network is probably the most common. In this case the relationship between the port voltages, port currents and ...
Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
There are six basic matrices that relate voltages and currents each with advantages for particular system network topologies. [4] However, only two of these can be extended beyond two ports to an arbitrary number of ports. These two are the z-parameters and their inverse, the admittance parameters or y-parameters.

Transducers can be analysed as two-port networks in the same way as electrical two-ports. That is, by means of a pair of linear algebraic equations or a 2×2 transfer function matrix. However, the variables at the two ports will be different and the two-port parameters will be a mixture of two energy domains.
When discussing 4-terminal networks, network analysis often proceeds in terms of 2-port networks, which covers a vast array of practically useful circuits. "2-port", in essence, refers to the way the network has been connected to the outside world: that the terminals have been connected in pairs to a source or load.

The behaviour of the two-port network in a larger network can be entirely characterised without necessarily stating anything about the internal structure. However, to do this it is necessary to have more information than just the A(jω) described above. It can be shown that four such parameters are required to fully characterise the two-port ...
The equivalent circuit for Z-parameters of a two-port network. The equivalent circuit for Z-parameters of a reciprocal two-port network. The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the port currents, port voltages and the Z-parameter matrix is given by:
