  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. 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 ...

  5. 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

  6. Network analysis (electrical circuits) - Wikipedia

    en.wikipedia.org/wiki/Network_analysis...

    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 ...

  7. Iterative impedance - Wikipedia

    en.wikipedia.org/wiki/Iterative_impedance

    Whereas an iterative impedance is formed by connecting port 2 of the first two-port network to port 1 of the next, an image impedance is formed by connecting port 2 of the first network to port 2 of the next. Port 1 of the second network is connected to port 1 of the third and so on, each subsequent network being reversed so that like ports ...

  8. 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 ...

  9. Nominal impedance - Wikipedia

    en.wikipedia.org/wiki/Nominal_impedance

    The ⁠ 1 / 2 ⁠ λ dipole and the ⁠ 1 / 2 ⁠ λ folded dipole are commonly taken as having nominal impedances of 75 Ω and 300 Ω, respectively. [13] An installed antenna's feed-point impedance varies above and below the quoted value, depending on its installation height above the ground and the electrical properties of the surrounding earth.
