Bait?  Bait?  Come come Jeff....  <smile>

In a perfect world, the crosstalk is zero.  In a real world, however,
there is crosstalk, unfortunately.  While the crosstalk is small, this
may or may not impact you depending on the signal levels that you have.

Imagine the following scenario:  You have a busbar, that is switched
on/off and 50 KHz, 2000 Amps.  You have a piece of coax laying near the
busbar, that has 50 uV signals on it.  

What do you think would happen to the signal on the coax?  I would bet
in this case that the coax would have some signal from the busbar on it.

See what I am driving at?
