Assessment and Requirements

Assessment of Academic Achievement

Exams will be administered throughout the course to assess the students' learning of the subject matter. All students will be required to complete a comprehensive final examination that assesses the learning of all course objectives. Students are required to conduct circuits laboratory experiments, and write reports about their findings.

General Course Requirements and Recommendations
  • Students must complete several homework assignments during the course of the semester. These assignments may be tied to the lecture, text, or lab, and require some design on the part of the student.

  • Students should complete at least one major computer project involving the design and analysis of a 1st or 2nd order circuit using a circuit simulation software package.


Text will be chosen from among recognized "major-level" texts.
