L= Lecture #
W=week of the year, starting from Jan 1
D=day: T is Tue, W Wed, R Thur, S Sat, etc.
The somewhat random-ordered numbers in front of many (not all) topics, are the topic numbers defined in the 2009 Syllabus Δ:
ECE-493 is divided into 4 basic sections (I-IV), divided into 40 topics, delivered as 24=4*6 lectures. There are two mid-term exams and one final. There are 12 homework assignments, with a HW0 that does not count toward your final grade. Each exam (I, II and Final) will count as 30% of your final grade, while the Assignments (HW1-12) plus class participation, count for 10%.

General information


All homework assigned on Tuesday will be due in class the following Tuesday. In 2009 there was no HW5 due to resource-constraints.


There are 3 exams total:
Exam I following Sections I, II, Exam II following Section III, Exam III following Section IV
The final is similar to the two midterms, and is only on the final 10 lectures on complex variables.
