**L**= Lecture #**T**= Topic #**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 2008 Syllabus:

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 (Prof's Discuression), count for 10%.
