Course Outline and Policy


This course intends to develop problem solving skills and understanding of circuit theory through the application of techniques and principles of electrical circuit analysis to common circuit problems. Subsequently, most common aspects such as filter realization and stability will be elaborated through frequency response analysis, feedback topologies etc. Broadly, the goals of the course are to inculcate understanding of: (a) waveforms, signals, transient, and steady-state responses of RLC circuits, (b) the ability to apply circuit analysis to AC circuits, and (c) advanced mathematical methods such as Laplace and Fourier transforms along with linear algebra and differential equations techniques for solving circuits problems.

Postconditions On the completion of this course the students will be able to:
1. analyze and synthesize simple electrical circuits.
2. find circuit response using Laplace transform.
3. understand signal superposition and Fourier Transform in the context of circuits.
4. use industry standard SPICE tools for simple circuit analysis and synthesis.
Evaluation Following components are part of the overall evaluation:
