Updated Table and Formula Sheets (3/4/2026)

The table and formula sheets that will be made available to you during this semester's exams have been updated to add the formulas for incident, reflected, and reactive power on transmission lines and available power from a signal source. A copy of the updated version is now available at the Moodle site in the Additional Resources section.

Remember that you may use two self-prepared handwritten help sheets during Exam #2 in addition to the table and formula sheet. I will give you only the first two pages of the formula sheet to use during Exam #2 since the third page refers to material that we have not covered yet.

List of Individual Investigation Topics (3/4/2026)

A list of representative topics that would be acceptable for the Individual Investigation assignment is now available on the Homework Assignments page. The list will be updated frequently.

The list is meant to serve as a source of ideas. You may select a topic from the list, but you do not have to. You may choose a topic that is not on the list.

You must choose a topic that is very specific and theoretical in scope and that requires a significant amount of mathematical and/or analytical work to explain. All topics are subject to prior approval.

More topics could be added to the list as the semester progresses.

Individual Investigation Assignment (3/4/2026)

A description of the Individual Investigation assignment is now available on the Homework Assignments page. A list of representative topics that would be acceptable for the assignment will be posted there soon.

Please contact me by Tuesday, March 17 if you wish to schedule your presentation during the week of March 23–27.
