Tough question. If you ssned me 4-6 answers with one being right and a link to a source, I'll post it in a future quiz <firstname.lastname@example.org>. This week's quiz is already loaded into the system and will appear at 0500 GMT on Friday. .
How about a question on the size of a reflection on a 1micron trace of 1cm length over a perfect insulator without termination. Driven by a perfect step function of 1V. What voltage level will the 3rd reflection be at the driven end? Extra credit- when will it happen...
I'd go along with Antedeluvian, getting the answers on the last page is fine for this quiz.
Zeeglen a couple of weeks ago gave us a schematic to puzzle over and let us stew for a few days, during which there were lots of comments about what it might be - but this is a different kettle of fish.
