Transmission info
« on: October 10, 2014, 08:27:46 AM »
I came across the following paper, discussing cable requirements and other aspects of vdsl, when trying to remind myself of some science that I have long since forgotten, in particular the Shannon-Hartley theorem.

The paper is (a) nice and short, (b) not too heavy going.   I especially like the descriptions of NEXT and FEXT, in terms of rude neighbours shouting.  :)
