Fundamentals of Signals and Systems Using the Web and MATLAB by Edward W. Kamen and Bonnie S. Heck (Prentice-Hall, 3rd edition, 2007).

Teaching assistant:
Hafeez Dhalla (al.dhalla [at]

Grades will be based on homeworks (30%), three in-class exams (45%), and a final exam (25%).

There will be a written homework assignment every week. The assignment will typically involve a couple of MATLAB exercises and a few textbook-style problems. I do not guarantee that all problems will come from the K&H textbook, though. The assignment will be posted on this webpage by 5pm every Tuesday, and due by 5pm the following Tuesday. Solutions will be posted on this page shortly after the homework is due. Absolutely NO late homework will be accepted.

Reasonable amount of collaboration on homework assignments will be tolerated. However, each student must write up his/her own solution. I am counting on your good judgment in following Duke policies on academic dishonesty.

Office hours:
TA: M 11:00-1:00 in the CIEMAS 2nd floor fishbowl
instructor: F 2:00-4:00 at the Perk (the coffee shop located at the Bostock Library)
