Reflections on the CAN bus - demonstration (subtitles)
The CAN bus is terminated with 120 ohms at each end to avoid reflections. Is it really necessary? What happens without terminating resistors? How do reflections work?
Discovered errors? Open questions? I like to answer your comments!

Please excuse the miserable photos. It had to be done quickly and there was little light. The oscilloscope's fan is also much too noticeable.
