ELEC 225, Fall 2012
Prof. Rich Kozick

Homework 2


Date Assigned: Monday, August 27, 2012
Date Due: Wednesday, September 5, 2012

  1. Reading: In the Ulaby/Maharbiz text, please continue to study Chapter 2, Sections 2-1 through 2-4, and also study Sections 2-5 and 2-6. I suggest you read Section 2-7 but we will not discuss it in class. Also, please begin studying Section 3-1 on the Node-Voltage Method (but we probably won't discuss this until the week of Sept. 10).

  2. Please check your schedule of exams and projects in other courses and compare with the tentative exam dates on the ELEC 225 syllabus. We will finalize the exam dates on Monday, Sep. 3.

  3. Please look at the lab roster posted on the ELEC 225 labs page and let me know if you would like to switch from the Thursday lab section to the Tuesday lab section.

  4. Schedule for the next 10 days (note there is no class on Wed., Aug. 29):

    Tuesday, Aug. 28: Meet at 1:30 PM in Dana 305 for a brief pre-course survey.
    Wednesday, Aug. 29: No class. (Class will be made up by having exams on Fridays.)
    Thursday, Aug. 30: No lab.
    Monday, Sep. 3: Class 9:00 - 9:52 AM in BRKI 66.
    Tuesday, Sep. 4: No lab.
    Wednesday, Sep. 5: Class 9:00 - 9:52 AM in BRKI 66.

  5. Please browse through the materials on Moodle under Course Materials for circuit analysis and solving linear simultaneous equations with TI-83/84 and TI-89 calculators. You should look through the document now to see the contents, and refer back to them as needed to perform computations in circuit analysis. Instructions are also listed for installing Matlab and OrCAD on your computer (this is optional).

  6. If you have not done so already, please complete the survey on Moodle titled "Background in matrix math and solving simultaneous equations" by 8 PM on Monday, Aug. 27.

  7. I suggest that you install the Multisim 11 software that came with the textbook on your computer, and run through the examples in Section 2-8. Nothing needs to be submitted, but work through the examples to become familiar with the software. We will use a different version of PSpice in lab (OrCAD), but you may want to become familiar with Multisim and OrCAD. You will need to know how to use OrCAD, but Multisim is optional.

  8. Please solve the following problems in Chapter 2 of the textbook and submit solutions in class on Wednesday, Sept. 5.
    Problems 2.14, 2.16, 2.22, and 2.23: All of these can be solved with Ohm's Law, KVL, and KCL without solving simultaneous equations. I suggest that you solve the problems this way, rather than writing node-voltage or mesh-current equations (we will do those methods next).
    Problems 2.26, 2.28, 2.33, and 2.34: Solve these by combining series/parallel resistors and look for voltage/current dividers. We will do some similar problems in class.
    Problem 2.29: Use source transformations (we will do a similar problem in class).
Thank you.
