Signals don't "know" anything. Like water following gravity, current =
(more precisely fields) will always take the easiest path. But indeed =
Kirchoff assures us the loop always has to complete at some point. Your =
task as a designer is to "think like an electron" (or more precisely =
"think like an EM wave") and make it go where you want it to go. =
"Ground" is a very convenient fantasy invented by engineers to simplify =
life, but there's really no such thing. =20

Subject: [SI-LIST] Should the signals always return back through GND
Hi SI virtuosi,
I am new to this group and to this field too.I have a
doubt thats buzzing my mind.I know you people
could help me out. My question is
Its always said that GND acts as a return path for a
signal.Do all the signals know that they=20
have to return back through GND and not through
anyother track in the signal layer having=20
lower impedance? What are the factors taken into
consideration to make sure that signals return
back through GND.
Waiting for your reply
Thanks in advance,
Nikita
