EGR 224/Spring 2019

EGR 224 is a required course for all students planning to earn a Bachelor of Science in Engineering Degree with the Department of Mechanical Engineering and Material Science at Duke University. It can also be taken as an elective by students in the Civil and Environmental Engineering Department who want their out-of-depertment course to focus on electronics, signal processing, and sensing. This page is meant to provide answers to general questions about the course, not necessarily specific questions about content. There is also a Category:EGR 224 that will list all pages relevant to EGR 224. Note at the bottom of this page that it is a member of that category.

Students in EGR 224 may also want to check out the Welcome Back page.
