Course description
This course is an introduction to the mathematical modeling and design of electrical, mechanical, and electromechanical systems. A system dynamical approach is used, which allows different energy domains to be modeled within a unified framework. Circuit elements covered include resistors, capacitors, inductors, diodes, transistors, and operational amplifiers. (Adopted from the course catalog.)

Homework, quiz, & exam policies
Homework & homework quiz policies
Weekly homework will be “due” on Fridays, but it will not be turned in for credit. However — and this is very important — each week a quiz will be given on Friday that will cover that week’s homework.
Quizzes will be available on moodle each Thursday (as early as I can get them up), and must be completed by Sunday (before midnight). Late quizzes will receive reduced credit.
Working in groups on homework is strongly encouraged, but quizzes must be completed individually.
Exam policies
The midterm and final exams will be inclass. If you require any specific accommodations, please contact me.
Calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communicationdevices will be allowed.
No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.
The final exam will be cumulative.
Grading policies
Total grades in the course may be curved, but individual homework quizzes and exams will not be. They will be available on moodle throughout the semester.

Academic integrity policy
Cheating or plagiarism of any kind is not tolerated and will result in a failing grade (“F”) in the course. I take this very seriously. Engineering is an academic and professional discipline that requires integrity. I expect students to consider their integrity of conduct to be their highest consideration with regard to the course material.
