Hi, Me again. Istvan sent me an interesting message off-list questioning Shive’s analogy between electrical open and mechanical clamped. His drift was "An electrical open 'feels' more like a mechanical free end." We agreed the answer might be of general interest so I’m posting an explanation here: http://signal-integrity.tm.agilent.com/2012/shive-wave-machine-allows-visualization-of-wave-properties#math Best regards, -- Colin ------ From: Istvan Novak [mailto:istvan.novak@xxxxxxxxxxxx] Sent: Tuesday, April 10, 2012 9:01 AM To: WARWICK,COLIN (A-Americas,ex1) Subject: Re: [SI-LIST] Re: Shive wave machine video Hi Colin, Thanks for posting the link. Very nice illustrations... I am at loss with one detail though. On the comparison chart among mechanical, electrical and acoustic transmission lines and reflections, I see short circuit describing open end (on the left of the screen capture), and open circuit for 'restrained' or shorted end. Does this make sense to you? Probably I am just not familiar with the nomenclature here...
