- g-parameters.

**What are the image parameters of two-port network?**

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, Zi 1, seen looking into port 1 when port 2 is terminated with the image impedance, Zi 2, for port 2.

**What is the condition of symmetry for two-port network find the condition for symmetry in terms of Z parameter?**

A two-port network is said to be symmetrical if the input and output ports can be interchanged without altering the port voltages and currents….Detailed Solution.

Two Port Parameters | Condition for Symmetry | Condition for Reciprocal |
---|---|---|

Z Parameters | Z11 = Z22 | Z12 = Z21 |

Y parameters | Y11 = Y22 | Y12 = Y21 |

### Which are the different interconnections of two port parameters?

Various types of Interconnection of Two Port Network such as series connection of two ports, parallel connection of two ports, cascade connection of two ports etc.

- Series Connection of Two Ports:
- Parallel Connection of Two Ports:
- Cascade Connection of Two Ports:
- Series and Parallel Permissibility of Connection:

**What is network parameters?**

Network parameters that may be monitored include the network load and rate at which errors occur. Both of these parameters have a time component, and hence it is important that the user understands the sampling period used by the network monitor.

**Where is two-port network used?**

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.

#### What is symmetry in two-port network?

A symmetrical two-port has the same characteristics at each of the ports. An example of a symmetrical network is a transmission line with a uniform cross section. A reciprocal two-port has a response at Port 2 from an excitation at Port 1 that is the same as the response at Port 1 to the same excitation at Port 2.

**What is meant by two port network?**

A two-port network (a kind of four-terminal network or quadripole) is an electrical network (circuit) or device with two pairs of terminals to connect to external circuits. In a two-port network, often port 1 is considered the input port and port 2 is considered the output port.

**When is a two port network said to be symmetrical?**

A two-port network is said to be symmetrical if the ports of the two-port network can be interchanged without changing the port voltages and currents as shown in 10.18(a) and (b), and the condition of symmetry is Condition of symmetry for Z-parameters. Condition of symmetry for Y-parameters, Condition of symmetry for T-parameters.

## Which is the best parameter for a two port network?

When two-ports are connected in a series-parallel configuration as shown in figure 14, the best choice of two-port parameter is the h -parameters. The h -parameters of the combined network are found by matrix addition of the two individual h -parameter matrices.

**How many independent variables does a two port network have?**

A two-port network has four variables with two of them being independent. If one of the ports is terminated by a load with no independent sources, then the load enforces a relationship between the voltage and current of that port. A degree of freedom is lost. The circuit now has only one independent parameter.

**What are the Y parameters in network theory?**

We will get the following set of two equations by considering the variables I 1 & I 2 as dependent and V 1 & V 2 as independent. The coefficients of independent variables, V 1 and V 2 are called as Y parameters. Y parameters are called as admittance parameters because these are simply, the ratios of currents and voltages.
