Objectives The student is expected to acquire fundamental skills in circuit formulation, circuit analysis and computer-aided simulation in both the time domain and the frequency domain.
Synopsis Measurement errors and their estimation. Lumped circuits and circuit components: ideal lumped circuit elements and analogies, independent and dependent sources, ideal transformers and gyrators. Introduction to the computer program SPICE. First-order and second-order circuits: zero-input response and zero-state response, complete response. Node and mesh analysis of linear time-invariant (LTIV) circuits: impulse, step and ramp responses. Sinusoidal steady-state response of LTIV circuits: phasor representation, phasor diagrams, network functions and frequency response, complex power and power factor. Coupled circuits and coupling elements: circuits with dependent sources, transformers and gyrators. Network theorems: superposition, Thevenin's and Norton's theorems, maximum power transfer. Network graphs and analysis: nodes and branches as linear graphs, cut-sets and loops, node analysis and mesh analysis, trees, cut-set analysis and loop analysis, proper trees and state equations for LTIV networks.
