ECEN 2250 – Introduction to Circuits & Electronics

Spring 2014 - MWF 9:00–9:50 am - ECCR 151 - Professor G. Moddel

Please check this page and the schedule regularly – Last update: 17 Apr 14

 

  • You might want to get started with the myDAQ mini-project due at the end of the semester. Please check out a myDAQ from the E-Store (across the hall from the main ECEE office).
  • The results of the in-class survey on textbook reading are shown here.
  • The steps to solving 1st order circuits with constant forcing functions are given here.
  • There will be an optional problem session every Wednesday for the rest of the semester.
  • To give you some more practice in solving circuits problems, I’ve added some practice problems. There are two sets of problems in the HW assignment.
    • The first (PP) are practice problems. You can discuss them with each other and with Courtnie and me, and they will not be turned in. I will post the solutions to these on Thursday.
    • The second set (HW) are the usual homework problems, to be done independently and turned in on Friday.
  • The exam solutions are posted below. The median scores are 44 (1st exam), 38 (2nd exam), and 41 (3rd exam).
