**On-Line Course**

A YouTube Channel (https://www.youtube.com/user/ECE345msu ) has been made to recreate the classroom experience for this ebook. This on-line version of the course is intended for non-ECE students at MSU. However these videos will also allow anyone, student, hobbyist or engineer (with the minimum background of an algebra course and an introductory course in calculus) to take this course at their own pace. You can find a suggested Self-Paced Instruction section near the end of this ebook.
