Information related to class matters will be announced in class and posted on the web site.
Assignments will be posted in class and on the course website. Assignment problems may require Spice simulations and/or self-study. Completed assignments should be turned in on the due date in class or at the assignment box located in the fourth floor in the ATAC building.
Late assignments:
Late assignments will be accepted until the solutions are posted.
Posted solutions:
Solutions will be posted after the due date.
Laboratory schedules will be posted in the lab area (AT 4001). All laboratory experiments must be performed and formal lab reports submitted by the assigned date. If the lab component of the course is incomplete, the maximum course grade will be 38.


No electronic device except non-programmable calculators are allowed in exams.

Midterm Exam:
date and topics will be announced in class.
Final Exam:
A three-hour final exam will be scheduled by the Registrar office.
Exam and assignment marks:
Students have one week to register complaints about how an exam or assignment was marked. Students who believe an error has been made in marking must write a statement making their case and take it to the instructor.
Marks distribution:
Assignments 10%, Laboratory 15%, max{Midterm, Final} 25%, Final 50%.
