**COURSE COORDINATOR: **Martin Plonus

**COURSE GOALS: **To provide the non-electrical engineering student with a foundation for understanding the basic principles of electrical and electronic systems. This course should help provide a solid basis for further studies, whether in the classroom or on the job. Because of the necessarily wide scope of the course topics and the time limitations of our 10-week quarter, the course is fast-paced. Success requires the student to attend all lectures and labs and to keep up with the reading and homework assignments.

**PREREQUISITES: **Mathematics 224 and Physics 135-2 or equivalent.

**GRADING: **Homework 20%; labs 20%; midterm 30%; final 30%
