Network Theory (PCECT205) Syllabus

Network fundamentals and analysis methods: concept of networks and circuits, circuit variables, ideal and practical sources, independent and dependent sources, source transformation, Kirchhoff's laws. Mesh analysis, node analysis, super-mesh analysis and super-node analysis applied to both DC and AC networks containing independent and dependent sources.

Network theorems and applications: superposition theorem, reciprocity theorem, Thevenin's theorem, Norton's theorem, Millman's theorem and maximum power transfer theorem for the analysis of DC and AC networks having independent and dependent sources.

Laplace transforms and transient analysis: Laplace transforms of standard signals and common functions, Laplace transform theorems (proof not required), inverse Laplace transforms, solution of differential equations. Transformation of basic signals and circuits to the s-domain with and without initial conditions. Transient analysis of RL, RC and RLC networks with DC, impulse, step and sinusoidal inputs. Analysis of low pass and high pass RC circuits using Laplace transforms.

Network functions and two-port parameters: network functions for single-port and two-port networks, properties of driving point and transfer functions, significance of poles and zeros, pole-zero plot. Impedance, admittance, hybrid and transmission parameters of two-port networks, reciprocity and symmetry conditions (derivation not required), inter-relationships between parameters, series and parallel connections of two-port networks.
