Network Theorems:

Superposition, Millman‘s theorems, Thevinin‘s and Norton‘s theorems, Maximum Power transfer theorem.

Transient behavior and initial conditions:

Behavior of circuit elements under switching condition and their Representation, evaluation of initial and final conditions in RL, RC and RLC circuits for AC and DC excitations.

Laplace Transformation & Applications:

Solution of networks, step, ramp and impulse responses, waveform Synthesis.

Two port network parameters:

Definition of Z, Y, h and Transmission parameters, modelling with these parameters, relationship between parameters sets.

Resonance:

Series Resonance: Variation of Current and Voltage with Frequency, Selectivity and Bandwidth, Q-Factor, Circuit Magnification Factor, Selectivith with Variable Capacitance, Selectivity with Variable Inductance.

Parallel Resonance:

Selectivity and Bandwidth, Maximum Impedance Conditions with C, L and f Variable, current in Anti-Resonant Circuit, The General Case-Resistance Present in both Branches.

Course Outcomes:

• At the end of the course, the students will be ableto
  
• Determine currents and voltages using source transformation/ source shifting/ mesh/ nodal analysis and reduce given network using star-delta transformation/source transformation/ source shifting.
  
• Solve network problems by applying Superposition/ Reciprocity/ Thevenin‘s/ Norton‘s/ Maximum Power Transfer/ Millman‘s Network Theorems and electrical laws to reduce circuit complexities and to arrive at feasible solutions.
  Calculate current and voltages for the given circuit under transient conditions.
  
• Apply Laplace transform to solve the given network.
  Solve the given network using specified two port network parameter like Z or Y or T or h.
  Understand the concept of resonance

Question paper pattern:

• Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
• Each full question can have a maximum of 4 sub questions.
  There will be 2 full questions from each module covering all the topics of the module.
  
• Students will have to answer 5 full questions, selecting one full question from each module.
  
• The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
