Textbooks
Required Text:
• Fundamentals of Electric Circuits, 4th Edition C.K.
Alexander and M.N.O. Sadiku, McGraw-Hill
– This book will be used again in ECE 3004
• PSpice for Basic Circuit Analysis, 2nd Edition, J.G.
Tront, McGraw-Hill.
Recommended Text:
• Mastering MATLAB 7, D.C. Hanselman and B.L.
Littlefield, Prentice-Hall, 2005.
Software
• Microsoft Office 2003 or 2007
• MATLAB (Students should already have this
from the freshmen package for engineers.)
• PSpice (version that comes with the Tront
book, version 9.1, or version 16.2)
Homework
• There will be 30 homework assignments due by
Saturday at 9 pm on the week in which they are
assigned.
– All must be submitted electronically through Scholar.
Assignments submitted with poor workmanship will
not be graded and a zero will be entered for that
assignment.
– Late submission and e-mailed assignments will NOT
be accepted and will receive a grade of 0.
– The lowest two homework grades will be dropped if
all 30 assignments are submitted, even if some of
them are late.
Attendance/Quizzes
• Attendance will be checked frequently and 1 point will be
given to those students who are in class. Occasionally,
questions on the lecture materials will be posted on Tests
and Quizzes at random multiple times during the semester.
1 point will be given for all appropriate answers that are
submitted before the quiz deadline.
– A replacement grade will be given to students who provide Dr.
Meehan with information on a volunteer activity that they have
done at some point during the semester.
– The lowest grade will be dropped when calculating the
contribution of these responses in the final grade for the course.
– A total of 5 extra points will be awarded to students who find
errors in the online lecture notes and provide lecture, slide
number, and a statement on the required correction.
Tests
• There will be three 50-minute in-class tests, given on
the dates specified in the course schedule.
– No postponements or makeup tests will be allowed except
in documented cases of hospitalization or situations of
similar severity. Students who need special
accommodations for the tests are encouraged to contact
Dr. Meehan early in the semester to make the necessary
arrangements. If a student takes all three tests and the
final, the lowest grade will be dropped.
– The tests will be closed book and closed notes. Students
will not be allowed to use computers or cell phones during
a test. No formula sheets will be permitted. Tests will be
conducted under a strict interpretation of the Honor Code.
Papers of students suspected of cheating will be turned
over to the Honor System without warning.
Final
• The final exam will be given on the date
specified and will last two hours. It will be
conducted under the same rules as the tests.

Announcements
• Virginia Tech IEEE student chapter is looking
for members, particularly ones that would like
to help with the SPAC (Student Professional
Activities Conference), which is held every
spring.

• Virginia Tech Eta Kappa Nu student chapter is
planning a 3rd Annual ANDY Board Design
Competition.
Class Preparation
• You should read the text, or listen/scan the
online lectures that I post, or find an internet
lecture to view on the topic for the coming
class each day.
– I do not plan to lecture very much during our
classes. I would like to discuss aspects of the
material that are covered in the text and lectures
and to go through the analyses.
• You should bring you computer with you to our next
class.
