ECE 280 - Electric Circuit Analysis

Students are expected to check their email regularly. Short notice changes: homework due dates, exam info, class delay/cancellation will be announced via email. It is the student's responsibility to keep the instructor informed of a current, frequently used, reliable, email address.

1. Course Description: Circuit analysis using superposition, equivalent circuits, transient and steady state analysis of RL, RC and RLC circuits. Applications of Laplace transform in circuit analysis, sinusoidal excitations and phasors, resonance, filters, AC steady- state analysis, coupled coils, and three phase circuits. PSPICE as a circuit analysis tool will be used. A lab demonstrating and investigating circuit analysis concepts is included. Students are expected to be familiar with basic circuit analysis terms and concepts (current, voltage, resistance, Ohm's Law and Kirchoff's Voltage Law) prior to entry into ECE 280 and are expected to have mastered the theory and manipulation of Laplace Transforms (via ECE 220 prior to the point in the class where they are applied (see Proposed Schedule).

2. Textbook: Introduction to Electric Circuits, 8th Ed., by Dorf and Svoboda, 2010.

3. Office Hours

4. Honor Code: All students are expected to abide by the George Mason University Honor Code. Sharing of ideas and comparison of answers on homework is acceptable, but copied work will not be accepted. In-class exams will be closed book and closed notes unless specifically stated by the instructor. All work must be your own. Any reasonable suspicion of an honor violation will be reported to the Honor Committee.

5. Grading: Exams (3)  45%
            Final Exam 30%
            Labs       15%
            Homework   10% 
6.Homework Policies: Homework will be assigned via email and Web page during the period a chapter is being covered. (Link from ECE homepage, Course Information, On-Line Course Materials, or directly: http://ece.gmu.edu/~wsutton/ece280doc.html). The homework will be turned in following completion of the chapter. One problem will be graded. Credit for attempting the others will be given. Late homework will not be accepted unless prior arrangements have been made with the instructor. Only partial credit will be given for late homework. Homework solutions will be posted on the course web page.

7. Grade Changes: A student requesting that the grade of a homework or exam problem be reconsidered must provide the instructor with the following information in writing within two class periods after the work is returned to the class:

7. Classroom Decorum: As part of professional development there will be no hats/caps worn in class. All students are expected to arrive on time. Pursuant to George Mason Policy, cell phones, pages, alarms, etc, will be totally turned off prior to the start of class. Laptops will be turned off. Electronic equipment violating this policy will be confiscated and held until the end of the week.
