      • Anything that is presented in class can be on the exam.
        • For example, there can be some problems about three-phase circuit. However, given that I only mentioned it quickly in class, try to think about what can I ask you.

  • Midterm exam information
    • Date: 25 Dec 2009
    • TIME: 09:00 - 12:00
    • ROOM: RS 407
    • The first page of the exam is posted.
    • There are 8 questions.
      • The first one is about resistor combination.
      • Some questions will ask you to use specific techniques. You must use the specified techniques. There will be no credit given if you do not follow the instructions.
    • See lecture 8 slides below for some review.
      • There is also Part 2 of the slides posted. This shows the solution of the two subquestions that we didn't have time to finish in class.
  • A corrected version of HW6 is posted. It change problem 4.22 to match the one given in the textbook. If you have downloaded the pdf file before, you only need to redownload question 4.22.
  • Because the tutor won't have his session on Dec 11, we will move the lecture one slot earlier. So, we will start at 9AM. In which case, we can end the class at noon. [Posted @ 10PM on Dec 4]
    • We will also return your graded old HWs.
  • A new version of HW4 is posted. The last three questions of the old version are moved to HW5. [Posted @ 4:30PM on Nov 29]
  • A new version of HW3 is posted. It fixes a small typo in the first question. If you use the textbook, there is nothing to be fixed. [Posted @ 10:40AM on Nov 26]
  • A lousy RSS feed for this page is created. All changes to the content below should be reported by the feed. [Posted @ 4:30PM on Nov 16]
  • As requested, complete HW questions are now posted. If you see any discrepancy between these posted questions and the questions printed in the textbook or the question numbers that I posted below, please inform me immediately. [Posted @ 6PM on Nov 14]
  • The tutorial this friday will be about basic Math. [Posted @ 2PM on Nov 3]
  • Welcome to ECS303! Feel free to look around this site. However, please keep in mind that it is still under construction. All posted information and documents are subject to change. [Posted @ 11AM on Oct 26]

General Information

Handouts and Course Material

Problem Set

Note that, for each HW, only ONE question will be graded. Of course, you do not know which one will be selected; so you should work on all of them.

  1. HW1
  2. HW2
  3. HW3
  4. HW4
    • Solve the following problems From Alexander & Sadiku - 4th Ed.
      4.6, 4.8, 4.12, 4.20, 4.27, 4.33, 4.36
    • Due: Dec 4 (Next Friday) @ 10:40 – in class
    • Questions 4.39, 4.45, 4.56 are moved to HW5.
    • If you use the textbook,
      • For 4.8, do not check with PSpice.
      • For 4.36, you must find the Thevenin equivalent seen the by 12-Ohm resistor.
    • Solution
    • Solution from the solution manual
    • Q4.27 was graded.
    • The scores for HW1-4 are posted here. The first column contains the last three digits of your student ID.
  5. HW5
  6. HW6
  7. HW7
  8. HW8
    • Solve the following problems From Alexander & Sadiku - 4th Ed.
      6.46, 6.49, 6.56, 6.71, 6.73
      7.1, 7.2, 7.3, 7.8
    • Due: Feb 5 @ 10:39 - in class
    • Hint: For Q7.2 and Q7.3, the time constant is the product of R and C. In this case, you have many resistors. What you need to do is to find the (Thevenin) equivalent resistance value at the capacitor's terminals. To do this, first take the capacitor out and then find the Thevenin resistance at the open terminals.
    • Solution
  9. HW9
  10. HW10
    • Due: Feb 19 @ 10:39 - in class
    • Solution
  11. HW11
  12. HW12
