Selected Answers to HW #1 (9/10/2025)

Answers to selected graded problems in HW #1 are now available via a link on the Homework Assignments page.

The purpose of this resource is to help you determine whether you are on the right track with your solutions. Remember that you must show all of the significant steps required to arrive at your answer to receive full credit for a given problem.

I might not be able to post answers for every homework assignment this semester, and/or at times the answers might be posted only a day or two before the assignment is due.

I try to double-check the answers before I post them, but there is a trade-off between speed and accuracy. Errors could be present in the posted answers. (There have been in the past.) If you believe that one or more of the posted answers is incorrect, please contact me as soon as possible.

Oscilloscope Screen Capture Information (9/10/25)

A link to a Dozuki page on capturing screen images on oscilloscopes is now available on the Laboratory page. Currently, this is the only easy way to capture screen images. Instructions for capturing images using Matlab and an attached computer will be provided soon.

Exam Schedule Confirmed (9/8/2025)

The exam schedule for the semester is now set at the following dates and times:

If you become aware of a serious conflict with one or more of these dates, please let me know as soon as possible. With enough advance notice, we might be able to move an exam, but it is unlikely at this point.

Reading Assignments for Sept. 8–12 (9/7/2025)

Subsection 2.6.3 was covered in class last week. It is being assigned for this Monday because it was inadvertently omitted from last week's reading assignments.

Subsection 2.4.0 is the introductory text for Section 2.4. You should always read the introductory text for each assigned section; however, Subsection 2.4.0 is highlighted here because it contains especially important information.
