Office hours with TAs Mon. through Fri. 6:00-8:00pm in the lab. There will be different TAs each evening so that we can cover all five nights. You can attend any evening.

Tutoring by Eta Kappa Nu is available for this course. Eta Kappa Nu (HKN) is the honor society for ECE students. The tutors are students who have taken the course in the past few years.

Announcements (Updated 17 September 2017)

(17 Sep 2017) (1) Lab 4 is now posted. We will probably not start it until Wednesday. There is no formal pre-lab activity but it would be a good idea to read the lab instructions. (2) Homework 2 is now posted on the ME site. It is due Friday. (3) If your Homework-1 grade was affected by the incorrect grading rules, please send me an email with the details and I will make the appropriate correction on the gradebook. (4) Monday we will discuss Chapter 4 in the text.

(14 Sep 2017) Today we'll begin with lab work. Finish Lab 3 if you have not done so. Also try Lab 2.5 (the light bulbs), and think about why your answers are surprising (assuming they are).

I have moved the homework deadline to Friday night as promised. There's a little "finish and save" button on the settings panel that I missed earlier.

Lab 3 reflections report is due Monday by 11:59 on Blackboard.

(11 Sep 2017) Remember there is a quiz at the beginning of class on Wednesday. There is no pre-lab for Lab 3. However, for this one we do require a report after the lab.

(Fri 8 Sep 2017) Homework 1 is now posted on the Mastering Engineering site, and is due next Thursday. You should be able to access this from the Blackboard site. If you have problems, let me know, and I'll work with the publisher. One note: On Mastering Engineering, values are usually reported to 3 significant figures, and the tolerance for a correct answer is 1 to 2 percent. If you are using a computer or calculator, you should have no problem getting answers close enough to be counted as correct. Often on an exam or lab, I'd accept a larger error; very frequently component tolerances are as much as 10%, and in such cases, I'd expect your answers to have a similar accuracy. I probably shouldn't admit that when I was a student, we did the calculations with a slide rule and it was just about impossible to get better than a few percent.

(Thu 7 Sep 2017) Monday I'll begin with a lecture and then we'll start Lab 2. Complete the prelab in your notebook before class (the material highlighted in yellow in the lab instructions). We will have a quiz at the beginning of class on Wednesday, and will begin Lab 3, which we should complete by the end of the week. There will be a homework assignment posted shortly.

(6 Sep 2017) For PRELAB tomorrow, there are two circuits on Page 1 of the lab writeup. Draw the circuits as you would build them on the forms on Pages 3 and 4. Do not build the circuits; just bring the drawings to the lab tomorrow. Page 2 shows a completed example.

(4 Sep 2017) The syllabus is posted above. I will use Blackboard for grading and for files that I don't want to share with the world (usually because they belong to someone else). Everything else will be posted here.

Welcome to EECE2150. I'll post announcements and other useful information here throughout the semester. Our first class is Wednesday, 6 September, 1:35 to 3:55 in 009 Hayden.

I'll have a syllabus posted on this site later this week or weekend. There is a note above about tutoring by HKN. That should be started in the second week of classes. We will be making use of Matlab and PSpice software. You probably have Matlab on your computer from your freshman GE course. PSpice can be downloaded if you have a Window's machine. You can also use it on the COE Virtual Lab. There will be more information about this later.

Textbook and Mastering Engineering Info:

There are three ways to gain access to the Mastering Engineering website, which will be used for this course.

1. To input the Mastering access code that you paid for at the NEU Bookstore. All Mastering access codes purchased at the bookstore grant access to the Nilsson eText. If you purchase a hard copy Nilsson text at the bookstore, they will want to make sure that it is packaged with the Mastering access code.

2. The bookstore is also stocking Mastering access code cards without the textbook.

3. You can purchase Mastering access directly from Pearson via the registration process. You will pay $111 (no markup) for Mastering access that includes the Nilsson eText.
You can also purchase Mastering access without the Nilsson eText, also via the registration process, for $61 (no markup.) This is a good option for the student who already has access to a hard copy of Nilsson.


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 .
Thanks to Prof. Onabajo and one of his students for instructions for Windows-10 users.

You may also use PSPICE on the COE Virtual Lab from anywhere, including off-campus. If you have good eyesight and small fingers, you can even use it on your phone.


Matlab is available to students, faculty, and staff for use on a home computer. See for more information. You may also use MATLAB on the COE Virtual Machine.

COE Virtual Lab

For information on the virtual lab, see There is a lot of useful software there, including PSPICE and MATLAB, and more.

Please note that there are going to be changes to the campus VPN in September 2017, so if you use the Virtual Lab off campus, watch for email from the University about the changes.

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.
