two-port network

A two-port network has four variables with two of them being independent.

The figure to the right depicts a circuit that contains a two-port network.

The Z-parameter matrix for the two-port network is probably the most common.

The feedback can be implemented using a two-port network.

The first step is replacement of the feedback network by a two-port network.

Most are built from simple two-port networks called "sections".

It can be shown that four such parameters are required to fully characterise the two-port network.

The available power gain of a two-port network, G, is defined as:

The input impedance of a two-port network is given by:

A two-port network is regarded as a "black box" with its properties specified by a matrix of numbers.

Start with a two-port network, N, with a plane of symmetry between the two ports.

There are four types of two-port network, and the selection depends upon the type of feedback.

Linear unilateral and bilateral amplifiers can be represented as two-port networks.

The concept of a two-port network can be useful in network analysis as a black box approach to analysis.

These kinds of circuits are commonly analysed and characterised in terms of a two-port network.

The two-port network model is used in mathematical circuit analysis techniques to isolate portions of larger circuits.

Usually a two-port network is implied but the concept is capable of being extended to networks with more than two ports.

The behaviour of the two-port network in a larger network can be entirely characterised without necessarily stating anything about the internal structure.

Power gain - for linear, two-port networks.

The theorem shows that any symmetrical two-port network can be transformed into a lattice network.

An example of a mirror with emitter degeneration to increase mirror resistance is found in two-port networks.

Where a network is composed of discrete components, analysis using two-port networks is a matter of choice, not essential.

If reverse direction transfer functions are ignored, a multi-port network can always be decomposed into a number of two-port networks.

An attenuator is a form of a two-port network with a generator connected to one port and a load connected to the other.

Taking an output from the end of this network, so realised, will transform it into a two-port network filter with the desired transfer function.
