## 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 […]

## Time Domain Response From Pole Zero Plot

Time Domain Response From Pole Zero Plot: From the locations of poles and zeros of the network function in the s-plane, the time response of the network can be perfectly identified. Let us study the various types of poles and their locations and the related time Time Domain Response From Pole Zero Plot. As stated […]

## 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 […]

## Poles and Zeros of Network Function

Poles and Zeros of Network Function: All the Poles and Zeros of Network Function have the form of a ratio of two polynomials in s as, The P(s) is the numerator polynomial in s having degree m while the Q(s) is the denominator polynomial in s having degree n. Hence network function can be expressed […]

## 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 […]
