Hello.
I've studied the electrical noise and it looks there are only two class of noise; differential-mode and common-mode noise.
Can all kind of noise be decomposed into differential-mode and common-mode noise? Is there any other kind of noise which can't be handled by typical counter-measurement for these two?
And right now, I'm confusing concept of common-mode noise when the noise source is external radiation shining whole electronic system. I guess the typical Common mode noise picture is the attached picture. This may represent the fact that noise source is 'external' to circuit. I've learn that common-mode noise has equal magnitude and polarity (phase) on both lines (Ex: live and neutral). But If chaotic radiation is the noise source, Is it really true that the noise are the same on both lines? I hardly imagine this.
