I have to disagree that this video is useless. We all could benefit from a better understanding of what happens in high speed circuits. I have spent many an hour working with a complicated piece of electronic equipment, and oscilloscope, and the need to have it do one thing while it is seemingly only capable of doing another. Understanding where those little squiggles in the oscilloscope trace actually come from is a tool to be working with that is almost invaluable beyond belief.
