The original set of AC analysis notes has been revised, with most of the changes occurring
in the last half-dozen slides. You should have another look at those pages.
A few examples of analyzing AC circuits are now available. More examples will be added soon.
Notes on AC power have been posted. (We just started into those at the end of class on Wednesday.)

We are not still not quite up to speed on AC analysis, so there will be
no quiz on Monday. On Wednesday, the quiz will definitely be on AC analysis.
In fact, all of the remaining quizzes this semester will be on AC analysis.
In class on Monday, we will go through as many AC example problems as we can
squeeze into 50 minutes. If ever there was a time when we need to see and
do as many example problems as possible, this is it.
Some AC analysis practice problems are available. At the moment, there
are relatively few different examples, but there are enough to get started.
A wider selection of practice problems will be made available over the next
All the homework solutions (except for the PSPICE problems) and quiz solutions are on the web site.
Several people who were not able to attend the help session the other night asked if
solutions to the
old exam could be posted. So, I've done that, including yet another way to find the
Thevenin equivalent of the first problem.
There will be a review session tonight in Room 0308 of Elings Hall, from 8:00 until whenever.
Attendance is not mandatory, but come if you have time and you have questions about
Thevenin equivalents, amplifiers, or RC/RL transients.

Reminder: Today's quiz will be on complex numbers (adding, subtracting, etc.).
Wednesday's quiz will be on AC analysis.
From the diminished expectations department: Exams will not be returned
until Wednesday. It is taking longer than expected to finish the final batch and
record all the grades.
Homework set G is available.

Monday's quiz will involve a calculation using cascaded two-port amplifier
models. The quizzes on Wednesday and next Monday (10/27) will have op-amp
questions. Practice problems for both are available.
Here is one version of the lab exam from
last year. Note that it mentions a 741 op amp. If there is an op-amp
circuit on this year's exam, it will use the 324.
There will be an exam review session on Tuesday evening (tonight)
from 8:00 p.m. to 10:00 p.m. in 205 Carver Hall. This is not mandatory
and no new material will be presented. The only activities will be answering
questions and working through example problems. If you feel like you need
a bit more help with the circuit concepts that we have been covering, then
you should try to attend.
Notes for superposition, which we will discuss on Friday, are on the
web site under the topics page.

The "super node" notes (from last Friday) are available. These might
help you with the last problem of HW set D, if you are struggling with
Sept. 18, 2014
The scores paga now shows quiz scores.
Solutions to HW A have been posted.
An updated version (minor changes only) of the node voltage notes has been posted.
Sept. 17, 2014
There were a couple of typos in homework problem 14 of HW C set that
may have caused confusion. Both parts of Prob. 14 should be done using
source transformation techniques. Also, the voltage label in the second
circuit was incorrect. These have been fixed.

I will not be in my office for office hours today. If you have an urgent
question, please send an email. I apologize for any inconvenience.
There are divider practice problems available. Although it is unlikely that
anyone needs much practice with such simple things.
Sept. 13, 2014
The description and accompanying materials for Lab 2 are available.
Sept. 11, 2014
In order to fix a problem with numbers not showing up in the Lab 1
instructions and template, the figures have been redrawn. The old
might look somewhat different at first glance, but they have exactly
the same information.
Sept. 9, 2014
Homework set B is available. (Due on Sept. 12.)
Sept. 6, 2014
The description and report templates for Lab 1 are on the web site.
Sept. 4, 2014
The numbers on homework problem 4 have been adjusted so that
they actually make sense. If you have already solved problem
4 using the original numbers, you do not need to re-work it
with the new numbers.
I will be in lab from 11:00 to about 11:45 on Friday, and so will
not be in my office for office hours during that time.
