Electromagnetic Compatibility (EMC) Principles 3rd Edition

Presented by Dr. Daryl Beetner, Professor, Missouri S&T

About the course

Electromagnetic compatibility (EMC) is the science behind building electronic products which do not cause electromagnetic interference and which are not susceptible to electromagnetic interference from other devices. This course is designed to teach the fundamentals of EMC. Topics range from what makes a good antenna, to regulations, to intelligent layout of printed circuit boards. While the course is based on solid math and physics, the lectures focus on developing the students’ understanding of concepts which enable the student to better apply the math and physics to sophisticated electrical systems.

The material contained in the EMC Principles Course was developed during the delivery of an introductory EMC course at Missouri S&T (Rolla). The DVDs include videos of class lectures and experimental demonstrations, as well course notes, assignments, assignment solutions, and practice exams. Watching the videos, doing the homework, and working through the exams should give you the same learning experience as our senior and graduate students at Missouri S&T.
