• Thévenin’s theorem, Norton’s theorem, maximum power transfer theorem;
• superposition;
• capacitor and inductor modeling;
• source-free response of RLC circuits;
• 1st and 2nd order RLC circuits, initial conditions, forced response, complete response;
• phasors;
• the Laplace transform;
• frequency response;
• high pass, low pass, bandpass, and bandstop filters;
• complex frequency, pole-zero and Bode plots, resonance;
• trigonometric form of Fourier series, complex form of Fourier series, Fourier transform techniques.

Learning Outcomes

At the end of this course, the student will be able to:

1. Use the basic DC circuit techniques to find current values, voltage values and power absorption values in a DC circuit containing ideal independent sources, resistors and dependent sources;
2. use practical sources and series/parallel rules to create equivalent circuits as a problem solving tool;
3. find basic Norton and Thévenin equivalent circuits and understand their utility;
4. understand the modelling of inductors and capacitors and their current-voltage relationships;
5. solve basic RL, RC and RLC circuits using established methods and understand how these solutions follow from the basic modeling;
6. be able to perform all the basic techniques (nodal and mesh analysis, superposition, Norton equivalents etc.) using phasors;
7. be able to perform all the basic techniques (nodal and mesh analysis, superposition, Norton equivalents etc.) in the s-domain using Laplace methods;
8. have some understanding of the utility and interpretation of the s-domain,
9. understand the complex plane plotting techniques and their uses for filter design and understanding resonance;
10. describe/define the characteristics of low, high, bandpass and bandstop filters.
11. be able to apply Fourier methods for circuit and signal analysis.
