Loop Matrix or Circuit Matrix: For a given directed graph, it is always possible to state which branches are involved in the formation of loops or closed circuits or meshes. For a given oriented graph,…
Define Incidence Matrix: Define Incidence Matrix consists of two parts, namely Complete Incidence Matrix Reduced Incidence Matrix Complete Incidence Matrix (Aa): Define Incidence Matrix is nothing but a mathematical model to represent the given network…
Network Topology: Basically network analysis is nothing but finding unknown branch currents or voltages across various branches. We can find these unknown parameters by using different network simplification techniques. These network simplifications involves basic Kirchhoff's…
V Shift and I Shift Method: V Shift and I Shift Method - A voltage source with a passive branch in series with it is called an accompanied voltage source. Similarly a current source with…
Network Equilibrium Equation in Matrix Form: In earlier section we have studied how to obtain equilibrium equations for a network which are based on loop analysis and node analysis. We can represent the same Network…
Indefinite Admittance Matrix: Consider Indefinite Admittance Matrix of a linear network with n terminals as shown in the Fig. 5.26. Let us consider a zero potential reference node or datum node arbitrarily outside the n-terminal…
Bode Plot in Network Analysis: The Bode Plot in Network Analysis is a popular method to obtain the frequency response of the networks. It basically sketches the variations in MR and ΦR against the frequency…
Complex Locus of RLC Networks: Complex Locus of RLC Networks - The network function G(s) or H(s) can be impedance function or an admittance function hence referred as immitance function. In the frequency domain G(jω)…
Magnitude Plot and Phase Angle Plot: Magnitude Plot and Phase Angle Plot - As mentioned earlier, the polar coordinate system is very commonly used to obtain the frequency response. The frequency ω is always an…
Frequency Domain Network Function: As the frequency domain network function is a complex function, it can be expressed mathematically in two ways i.e. using rectangular coordinates or using polar coordinates. In rectangular coordinates it can…
