Four Terminal Network

Four Terminal Network:

Asymmetrical Network in Network Analysis : An asymmetrical network has following electrical properties, Iterative impedance Image impedance Image transfer constant Iterative impedance (Z′0): Consider that infinite asymmetrical networks having identical electrical properties are connected in cascade as shown in the Fig. 8.4 (a) and (b). The iterative impedance is the impedance measured at one pair of terminals of the network in the chain of infinite networks as shown …


Half Section in Four Terminal Network : The Half Section in Four Terminal Network can be obtained by splitting symmetrical T and π networks into two identical networks. The half sections obtained by splitting shunt arm of symmetrical T network in two equal impedances and series arm of symmetrical π network in two equal impedances are identical as shown in the Fig. …


L Section in Four Terminal Network : L Section in Four Terminal Network is very much similar to half section consisting series and shunt arm impedances Z1 and Z2 respectively as shown in the Fig. 8.28. The ladder network can be analyzed into a series of L sections rather than T and π sections. The main application of L section is in …


Lattice Network in Network Analysis : The Lattice Network in Network Analysis is a symmetrical and balanced with four arms as shown in the Fig. 8.21 (a). The arms consisting impedance ZA are called series arms of the lattice network. The arms consisting impedance ZB are called shunt or diagonal arms. The lattice network can be rearranged in the bridge structure as …


Symmetrical Network in Network Analysis : A symmetrical network has two important properties as Characteristic impedance (Z0) Propagation constant (γ) The two networks having the same electrical properties i.e. characteristic impedance (Z0) and propagation constant (γ) are called equivalent networks or identical networks. Characteristic Impedance (Z0): Consider that infinite number of identical symmetrical networks are connected in cascade or tandem as shown in the Fig. 8.1 (a). …


Symmetrical pi Network in Network Analysis : The Symmetrical pi Network in Network Analysis is another important network in line transmission fulfilling the conditions of total series and shunt arm impedances as Z1 and Z2 respectively. Thus the series arm impedance of a it network is selected as Z1 and to have a total shunt arm impedance of Z2, each shunt arm …


Symmetrical T Network in Network Analysis : In line transmission theory, the symmetrical T network is the most frequently used network. The condition in the symmetrical T network is that the total series arm impedance and shunt arm impedance must be Z1 and Z2 respectively. To have a total series arm impedance of Z1, the two series arm impedances must be selected as …
