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 […]

s domain

s domain: To Understand the concept of s domain network, let us see the below three points Single Resistor in s Domain Single Inductor in s Domain Single Capacitor in s Domain Single Resistor in s Domain: Consider a single resistor, carrying a current i(t) shown in the Fig. 3.1. The voltage across it is […]

Convolution Integral in Network Analysis

Convolution Integral in Network Analysis: The Convolution Integral in Network Analysis in Laplace transform states that where f1 (t) * f2 (t) = Convolution of f1 (t) and f2 (t) From the definition of system function, Taking inverse Laplace, From the convolution theorem, where Thus with the help of convolution of e(t) and h(t), the response of the network […]
