(10 Dec 2018) Exams are graded and course grades have been calculated. Here are the exam histogram, the course histogram, and the Exam 3 solutions. Thanks to all of you for your participation in the course. I hope to see you in a future course and I wish you the best in the future.
(3 Dec 2018) As exams are approaching, I will hold extra office hours Tuesday, 4 December, from 12:30 to 2:00PM, in the lobby of the ISEC Building. Notice the Location: I will not be in my office.
(30 Nov 2018) Here are some practice exams to prepare for Exam
3.

(28 Nov 2018) Homework 12 has been updated. Specifically Problem 7 was not solvable in the original. See the updated file now posted. Mengting has already sent an email about this, but now the file is posted.
If you are interested in learning about the making of transistors rather than just using them as we've been learning in this course, please have a look at E-4604-Flyer.pdf, for information about an advanced course.
(26 Nov 2018) We have official confirmation of our final exam, Thursday, 6 December, 12:00 to 14:00 in 424 Hayden.
(26 Nov 2018) There was an error in posting HW11. The correct file is now posted.
(26 Nov 2018) I had a minor ski injury yesterday and I won't be walking very well for a couple of days. I'm going to cancel class today, but I do expect to be back on campus Wednesday.
(21 Nov 2018) Happy Thanksgiving. I've finished grading Exam 2 and have posted the scores on Blackboard. For your information, here are the solutions and Grade Statistics. In the first figure, you can see your rank in the class for both exams to date, and in the second, you can see how individual scores compared across the two exams. Overall, I'd say this one is much better.
(20 Nov 2018) We have our final exam scheduled for Thursday, 6 Dec in HA424 for 12:00 Noon to 2:00PM. The email I received said "tentative" and I'm not sure quite what that means. It looks very official, so I assume it came from the scheduling office.
(17 Nov 2018) The other sections have postponed the due date for the project, HW8/9 to 29 November, which is a bit later than I said in class. However, because of the tight schedule, we are keeping the due dates for 11 and 12 unchanged; 28 November and 5 December respectively. You will have one assignment due on the 28th (HW 11) and another due on the 29th (HW 8/9), so please plan accordingly.
(9 Nov 2018) Here are a couple of practice exams for Exam 2 on BJTs;

(8 Oct 2018) Here are some practice exams for Exam 1. Wednesday
will be a review day to discuss what will be on the exam.

(1 Oct 2018) Solutions to HW2 are now posted. HW3 is due Wednesday, 3 October, as announced in class. Note that there was an error in the figure for the last problem in that two figures were shown. The correct version (including the data) is now posted. You should have a version that says it is due 3 Oct, and is entirely on one page. There are some similar issues with HW4-6, and those will be re-posted shortly.
(23 Sep 2018) Homeworks are posted up through HW6.
(10 Sep 2018) Note that Mengting's office hours are moved to 505 ISEC, and not 405. There was a conflict with that room.
(7 Sep 2018) The first three homeworks are now posted. Homework 1 is due next Wednesday at the start of class.
(23 Jul 2018) Welcome to my section of EECE2412, Electronics.
Please look here first for course information. I do like all the
pointing and clicking that's required to use Blackboard, so I post
most information (except grades) here.
We will introduce
you to the basic components of modern electronics, namely diodes and
transistors, along with their use in a variety of circuits. There
will be lectures, homework assignments, computer-based design
assignments, and of course, exams. The laboratory, EECE2413, will be
closely coordinated with the class material. The
textbook, is Hambley,
Electronics , Second Edition.
We will make use of Pspice and Matlab software in this course.

Pspice information (Thanks to Prof. McGruer) PSpice (Available on NU
computers or download for free). We will extensively use PSpice. The
student version of PSpice is available for free. You may use any
version of PSpice that you wish, but you may find it helpful to
be consistent in your versions. You cannot save in version 9.1 and use
in version 8.0. In fact, sometimes there is difficulty in saving in
version 8.0 and then using in version 9.1, but less so.
Pspice is avaliable at
http://www.electronics-lab.com/downloads/schematic/013/ .
Thanks to Prof. Onabajo and one of his students
for instructions
for Windows-10 users.
If you want to review circuits or more problems to solve in electronics, you might find Schaum's Outlines for Electric Circuits or Electronic Devices and Circuits useful. I have not looked at these in a while but I found their earlier outlines quite useful when I was a student.
ABOUT THE BACKGROUND: My favorite winter passtime is skiing. I put this background together from a detail of a photograph taken at Park City, in 2003. There are four copies in different orientations so that the tracks (and more importantly, the brightness levels) line up as the pattern repeats.
