Just a clarifcation of what noise is:
Well use Russ's audio analogy since you can hear it.
Noise is just many frequencies over a frequency range which we don't understand. You can hear a single tone or some combination
like an orchastra playing and make sense of them. But all that hiss or crackling is just noise. They both exist and depending on the amplitude of one to the other one may dominate.
The same applies to higher and lower frequencies out of our hearing range.
A good example of noise would be sparking from brushes of a motor which puts out high noise levels ie; many random frequencies
through out the spectrum . Should see what happens when tig welding welding is done and a computer is on and near by.....
heck wiped my friends hard drive.
So if you cut a energy field, say one with a whole bunch of noise, with a wire, a flow of noise electrons will occur on the wire and you can measure the voltage. The noise was inductively coupled from a radiating source. So if the noise level is high compared to the
a signal that you were sending on the wire, the noise would dominate and say a device recieving it could not process it.
Sorry for the crap explainations as most of the tech stuff is saved to memory and just can't seen to find the folder it was place in!
What do you mean by ...induced into a "SCREEN".
