Evaluation of Residue Using Pole-zero Plot

Evaluation of Residue Using Pole-zero Plot: The behavior of a network can be predicted only by looking at the pole-zero plot. The poles are the complex frequencies explaining the time responses. Also zeros are useful in finding partial fraction expansion. In this section, we will discuss graphical methods for obtaining the residue i.e. partial-fraction expansion […]

Pole Zero Plot

Pole Zero Plot: Pole Zero Plot – The variable s is a complex variable. Hence a complex plane is required to indicate the values of s graphically. A complex plane is a plane with X-axis as real axis and Y-axis as imaginary axis. The real axis is denoted as σ axis while imaginary axis is […]

Driving Point Function

Driving Point Function and Transfer Function: For a given network, the ratio of Laplace transform of the source voltage and source current is called driving point function. If it is a ratio of source voltage to source current, it is called driving point impedance function denoted as Z(s) while if it is a ratio of […]

Transfer Function or Network Function

Transfer Function or Network Function: Every network is designed to produce a particular output, when input is applied to it. The network performance is judged by studying its output for the applied input. The output is the effect of network parameters on the applied input. Thus once the network is designed, the effect of network […]
