ECE 3004 AC Circuit Analysis (3C)
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.
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.
Typically offered: Fall, Spring. Program Area: Circuits and General.
Prerequisites: C- or better in 2704. Corequisite: 3074.
ECE 2704 is a prerequisite because it develops the mathematical methods of Laplace and Fourier transforms that are applied to ac circuit analysis in ECE 3004. The corequisite of 3074 is required because it is the accompanying laboratory that develops experimental skills in the subject matter of the course.
