Recommended for those who want more help:

Karu, Signals and Systems Made Ridiculously Simple, ZiZi Press.

Computer Facilities: The Matlab system will be used throughout the semester. While it is available on various machines in the Media Lab, we strongly encourage your getting an Athena account and working from there. For on-line help see Athena's Matlab Information Pages.

Handouts: Handouts should be available on this web site in a timely fashion, if you miss class, or misplace your paper copies. If what you want isn't there, ask the TA.

Exams: There will be two in-class quizzes. Both are open-book and open-notes, and we suggest bringing along a calculator that knows about trigonometric functions.

Grading: Your grade will be determined as a weighted average: 40% homework, 50% quizzes, 10% class participation.

Obligatory Policy Statement: We think collaboration is a fine thing, and encourage studying in groups and discussing the topics covered in class. However, for homework problems the work you hand in should be done at least 95% by you alone. If you can think of a system that gives a good evaluation of individual performance and is even better at facilitating learning of this material, please suggest it to us.

Late Homework: We realize that many of our students lead complicated and demanding lives, and will allow you to hand in up to two problem sets late - without penalty - as long as you get permission from one of the faculty or TAs at least a day in advance of the regular due date. The delay is limited, however, and under no circumstances will you receive credit for a problem set after we have made available the solutions.
