Introduction to Electronics

Semester 2

This course will adequately review the electronics content of CAPE Physics with extensions into slightly more advanced topics. Students will be introduced to basic concepts in analog and digital electronics, basic semiconductor theory, and analog communication systems (AM, FM, and PM). This course is required for all electronics engineering students and electronics majors and minors. The lab component for this course is offered as a separate teaching lab course (ELET1405).
