I may not have been clear enough. I meant that the "injection" (near) end would be terminated in the proper impedance to prevent ping-ponging of the pulse. The far end would be left as you said, either open (most likely) or shorted. :-) michael -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
