Complex Numbers Tutorial

The course material was structured assuming all students possessed basic familiarity with complex numbers. If you are not entirely comfortable with complex numbers, here are a few tutorials that should help you out as far as this course is concerned:

Note: Some of these tutorials might refer to the imaginary number as i (i^2 = -1), whereas others might refer to it as j (j^2 = -1). Both refer to the same quantity; although in EE, using j is preferred since i has been historically reserved for representing (ac) current.
