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.

In electrical circuit theory, a port is a pair of terminals connecting an electrical network or circuit to an external circuit, as a point of entry or exit for electrical energy. A port consists of two nodes (terminals) connected to an outside circuit which meets the port condition – the currents flowing into the two nodes must be equal and ...
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 "two port" representation is a state space reduction from the real network equations Vx=Zx Ix which in this case would be 4x4 . A way to look at the assumption made in the reduction is that the current flowing into the input top node is balanced by the current flowing out of the bottom node of the input; similarly for the output.
Darlington showed that any PRF can be realised as a two-port network using only L and C elements with a single resistor terminating the output port. [89] The Darlington and related methods are called the insertion loss method. [90] The method can be extended to multi-port networks with each port terminated with a single resistor. [91]
Usually a two-port network is implied but the concept can be extended to networks with more than two ports. The definition of image impedance for a two-port network is the impedance, Z i 1, seen looking into port 1 when port 2 is terminated with the image impedance, Z i 2, for port 2. In general, the image impedances of ports 1 and 2 will not ...
Start with a two-port network, N, with a plane of symmetry between the two ports. Next cut N through its plane of symmetry to form two new identical two-ports, 1 / 2 N. Connect two identical voltage generators to the two ports of N. It is clear from the symmetry that no current is going to flow through any branch passing through the ...
