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:

1. The number of the problem(s) to be reconsidered;

2. A description of your mistakes made in the problem(s); and

3. The reason that you feel that you should receive additional points
for the problem(s).
i.e. material the instructor did not see that was on the exam or
homework paper.

Note: The entire exam or homework may be reconsidered by the instructor
at this time.

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.
