Has anyone ever tried to fake creating a twisted-pair on a

doing so on a recent board and our testing indicates that it

think it is a waste of time to even attempt it but some people
here think it
is helpful.
I did this on one board that had analog differential signals right next
to
10 A, 80 V pulses with 40-100 nS Tr. It probably works, as there was no
measurable crosstalk on the analog signals. I didn't however, make the
board
both ways and compare. I wouldn't even bother with two comparable
low-level
signals.
