Course Objectives
The objective of this course is to apply knowledge of mathematics (namely algebra and calculus, complex variables and series) and engineering (basic circuits) to make important insights on the signals (that is a stream of data) and the systems (that process signals). Various classes of signals and systems will be introduced with a special focus on the important subclasses.
This course is basic to the field of communications (ELEC 461 and subsequent courses), control (ELEC 372 and subsequent courses) and signal processing (ELEC
442).
Prerequisite
ELEC 261 Complex Variables.
Assignments
Homework is an essential part of this course. There will be eleven weekly assignments and the best ten marks you receive will form 10% of the final grade.
Homework will be assigned every Friday and will be collected the following Friday.
Late homework will not be accepted.
Each homework will consist of two sets of problems: required and optional. All problems will be corrected by the TA but only the required problems will be marked.
Exams
There will be one midterm in addition to the final comprehensive examination. There will be no make-up exams.

All exams will be closed book. However the students are permitted to bring in with them one 8.5*11 inch sheet of paper, written on both sides. Anything may be written on this paper. Students may photocopy things and tape/glue them to their crib sheet.
However the taping/gluing must be on all 4 corners so that the attachment is not a
"flap" that can be lifted up and more written underneath. The surface area available is only for the one 8.5*11inch piece of paper. Only non-programmable calculators are allowed.
