Describing a network that has only two terminals, comprising a single port, that are used to connect it to other parts of a circuit. The behaviour of a one-port network is usually described by the impedance between its terminals. All the basic electronic components, such as resistors, capacitances, and inductors, can be represented as one-port networks, as can simple combinations of these. The one-port network provides the basis for much of circuit analysis, and for many circuit synthesis techniques.
