Most of the videos in this module and all the other modules were shot in front of a live class in spring, 2016. As a result, there are references made to due dates for assignments that do not apply to the current class. Please ignore these references. For due dates, please consult the schedule on Blackboard.

Videos for ECE 252 are available for streaming and for downloading. The streamed videos are from YouTube and allow quick access to the content. When a video is playing, you may click the box on the lower right of the screen to expand the video to the full screen.

The downloaded versions can be stored permanently on your computer. Most of these downloaded versions contain two video streams, one of the computer screen and the other of the professor.
