# ECE 3004 - AC Circuit Analysis (3C)

Course Description

Application of the basic laws and techniques of circuit analysis to ac circuits. Complex numbers and algebra with an emphasis on phasor representation of circuits. Calculation of the frequency response of circuits with R, L, and C components, independent sources, controlled sources, and operational amplifiers. Analysis of AC steady-state circuits and determination of average power. Magnetically coupled circuits. Laplace and Fourier transforms. Representation of circuits by two-port models.

Why take this course?

Circuit analysis and design using discrete R, L, and C components is the most fundamental skill for electrical engineers. This course stresses the AC analysis of basic circuit elements and teaches modeling, design, and analysis skills for AC circuits. It also covers such topics as: magnetically coupled circuits and their application to transformers; frequency response and active and passive filters; the application of Laplace transforms and Fourier series and transforms to analyzing circuits; and two-port circuits.
