(SEM IV) THEORY EXAMINATION 2022-23 NETWORKS ANALYSIS & SYNTHESIS

SECTION A – Short Answer / Conceptual Part

Section A contains brief 2-mark questions covering fundamental network theory concepts.
From the part you shared, it includes:

Definitions of Tree, Co-tree, Twigs, Links in a network graph.

Drawing an oriented graph from a given incidence matrix.

Expression of maximum power transfer.

Statement of the Reciprocity theorem.

Difference between natural response and forced response of a network.

Discussion of underdamped and overdamped conditions in a series RLC circuit.

Definition of Z-parameters and Y-parameters of a two-port/four-terminal network.

Conditions for a network to be reciprocal and symmetrical.

Names of two synthesis methods for a positive-real function.

Any two properties of network functions (like passivity, stability, causality etc., depending on full question).

This section tests basic theory, graph concepts, transient behavior, two-port parameters and synthesis basics.

SECTION B – Descriptive / Problem-Solving Part

Section B asks to attempt any three questions, each normally of 10 marks (from the pattern you’ve shown earlier).

From Q2(a), it includes:

Explanation of the principle of duality in electrical networks.

Determining the dual of a given network (the circuit will be given in the full paper).

Other questions in this section (not fully shown in your text) will typically involve:

Network theorems (Thevenin, Norton, Superposition, Reciprocity, Maximum Power Transfer).

Mesh and nodal analysis, source transformations.

Graph theory applications, cut-set and tie-set equations.

RLC transient analysis in time domain.

This section checks your ability to apply theory to solve numerical problems and derive relationships.

SECTION C – Long / Advanced Network & Synthesis Problems

Though not fully visible in your pasted text, from the syllabus and pattern of KEE 403, Section C normally includes:

Two-port network analysis using Z, Y, h, ABCD parameters and conditions for symmetry/reciprocity.

Frequency response, resonance, bandwidth problems for RLC networks.

Positive real functions, Hurwitz polynomials, and their use in network synthesis.

Driving point and transfer function synthesis using Foster and Cauer forms.

You are usually asked to attempt one part from each question number (e.g., 3(a) or 3(b), 4(a) or 4(b), etc.), each of 10 marks, involving derivations, proofs, synthesis steps, and design-oriented numerical problems.
