If you liked using the AD2 from ECE 3 well you're in luck because this class uses the AD2 for the entire quarter. You learn about basic circuits (matching the pace with ECE 10/ECE 10H), from voltage dividers, up to multi-order RLC circuits. 4 labs, 4 reports (roughly 8 pages long), assigned every two weeks, with the lab specs for the entire quarter published at the start of the quarter. The labs and reports are expected to be completed by each individual. Lots of people cram doing the lab and the report 48 hours before it's due. You will likely also do that too. If you decide to do the labs early and do the report later, you'll likely have to repeat doing the lab as well. Lab sections are not mandatory, EXCEPT for the days your reports are due, as for my quarter there was a "quiz" and practical demo required for checkoffs. For the checkoffs, I partnered up with a friend, but that policy is up to your TA.
