Oh said:Unshielded Twisted Pairs cancel noise out, only because each line recieves
equal amount of noise, and Hence at the *Balanced* line RECEIVERS there is
Delta V = ~0 at about any place on the twisted pairs as a result
of EM noise from the environment, assuming that it's wavelength
is at right angles to the lines and it's wavelengths far larger than
the pair conductor to conductor distance (excluding speed of
light changes said:the actual noise cancellation occurs AT the receivers,
How did it get there?
and ONLY if they are
balanced on each end... like computer network cables.
If your communication cable setup is not balanced at each end, then the
magical noise cancellation disappears, and in fact you'll get quite a bit of
You could add a rectifier and get free energy, right? Just from
the thermal background noise ...
