Two Port Network Characterisation : Gain, Bandwidth, Noise Figure
4.Two-port Network Characterization:
A two-port network can be represented as below:
The noise in a circuit can be characterized by the following parameters:
Noise Figure, F
Assuming that the input is driven by noise temperature at T, the output noise of the two-port network is given by kTGBF, where G is the gain, B is the
bandwidth, and F is the Noise figure of the circuit under consideration.
