  2. Two-port network - Wikipedia

    en.wikipedia.org/wiki/Two-port_network

    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.

  4. Admittance parameters - Wikipedia

    en.wikipedia.org/wiki/Admittance_parameters

    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 ...

  5. Impedance parameters - Wikipedia

    en.wikipedia.org/wiki/Impedance_parameters

    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:

  6. Scattering parameters - Wikipedia

    en.wikipedia.org/wiki/Scattering_parameters

    The Scattering transfer parameters or T-parameters of a 2-port network are expressed by the T-parameter matrix and are closely related to the corresponding S-parameter matrix. However, unlike S parameters, there is no simple physical means to measure the T parameters in a system, sometimes referred to as Youla waves.

  7. Propagation constant - Wikipedia

    en.wikipedia.org/wiki/Propagation_constant

    In the context of two-port networks and their cascades, propagation constant measures the change undergone by the source quantity as it propagates from one port to the next. The propagation constant's value is expressed logarithmically, almost universally to the base e, rather than base 10 that is used in telecommunications in other situations.

  9. Reciprocity (electrical networks) - Wikipedia

    en.wikipedia.org/wiki/Reciprocity_(electrical...

    If a current, , injected into port A produces a voltage, , at port B and injected into port B produces at port A, then the network is said to be reciprocal. Equivalently, reciprocity can be defined by the dual situation; applying voltage, , at port A producing current at port B and at port B producing current at port A. [1] In general, passive networks are reciprocal.
