• properties of linear networks;
• 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;
• transients and 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, circuit analysis using Fourier series expansion, Fourier transform techniques.

## Learning Outcomes

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

• 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;
• use practical sources and series/parallel rules to create equivalent circuits as a problem solving tool;
• find basic Norton and Thévenin equivalent circuits and understand their utility;
• understand the modeling of inductors and capacitors and their current-voltage relationships;
• solve basic RL, RC and RLC circuits using established methods and understand how these solutions follow from the basic modeling;
• be able to perform all the basic techniques (nodal and mesh analysis, superposition, Norton equivalents etc.) in the s-domain using Laplace methods;
• have some understanding of the utility and interpretation of the s-domain,
• understand the complex plane plotting techniques and their uses for filter design and understanding resonance;
• describe/ define the characteristics of low, high, bandpass and bandstop filters.
• design passive filters with specific corner or cutoff frequencies.
• be able to apply Fourier methods for circuit and signal analysis.
