  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.

  3. 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:

  4. Image impedance - Wikipedia

    en.wikipedia.org/wiki/Image_impedance

    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 ...

  5. Performance and modelling of AC transmission - Wikipedia

    en.wikipedia.org/wiki/Performance_and_modelling...

    In a two-port network, often port 1 is considered the input port and port 2 is considered the output port. The two-port network model is used in mathematical circuit analysis techniques to isolate portions of larger circuits. A two-port network is regarded as a "black box" with its properties specified by a matrix of numbers. This allows the ...

  6. 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 ...

  7. 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.

    British Airways is overhauling its loyalty program to reward spending instead of miles flown. It will offer more chances to get points while making status harder to achieve for leisure travelers.

  9. Lattice network - Wikipedia

    en.wikipedia.org/wiki/Lattice_network

    z-parameters, or Impedance parameters, are one set from the family of parameters that define a two-port network, with input and output values defined by I 1, I 2, V 1 and V 2, [12]: 254 [25]: 29 as shown in the figure. Two-port Network. Equations defining network behaviour in terms of z-parameters are
