## Transfer Function of Terminated Two Port Network

Transfer Function of Terminated Two Port Network: A ratio of voltage or current at one port to the voltage or current at the other port is called a Transfer Function of Terminated Two Port Network. In the last sections, we have studied how to obtain two port network parameters. In this section, we will study …

## Bridged T Network Analysis

Bridged T Network Analysis: Consider Bridged T Network Analysis as shown in the Fig. 6.15 (a). We can consider bridged T network as a parallel connection of the two networks as shown in the Fig. 6.15 (b).

## Condition for Reciprocal Two Port Network

Condition for Reciprocal Two Port Network: If the ratio of voltage at one port to the current at other port is same to the ratio if the positions of voltage and current are interchanged, then the network is said to be Condition for Reciprocal Two Port Network. The transfer impedances can be measured as shown …

## Condition for Symmetry in Two Port Network

Condition for Symmetry in Two Port Network: If the impedance measured at one port is equal to the impedance measured at the other port with remaining port open circuited, the network is said to be Condition for Symmetry. The impedances at two ports can be measured as shown in Fig. 6.6 (a) and (b). Condition …

## ABCD Parameters of Two Port Network

ABCD Parameters of Two Port Network or Transmission Parameters or Chain Parameters: ABCD Parameters of Two Port Network are known as transmission parameters. These are generally used in the analysis of power transmission in which the input port is referred as the sending end while the output port is referred as receiving end. These are …

## h Parameters of Two Port Network

h Parameters of Two Port Network: h Parameters of Two Port Network are also called hybrid parameters. These parameters are very useful in constructing models for transistors. The transistor parameters cannot be calculated using by either short circuit admittance parameter or open circuit impedance parameter measurement.
