I agree with your examples of DC power supplies and AC noise. Been there,

Defining how may angels can dance on a DC power cable without having to
redefine it is pointless, however. Everyone I knew in the telco industry
had good, workable terms for the cause of the need for filters, not only at
the FB, but at the equipment rack too; it was noise, trash, crap.
spikes....., but the 48V and 130V "power" were always DC and we knew the
noise had to be dealt with as AC riding the DC. No other esoteric, mindless
definitions are needed even though the terms AC and DC may be misnomers.
They are historic and work very well.

Exactly.

LOL, instead of grasping at straws you're now grasping for the
coattails of someone who knows what he's talking about, and you're
using that "Exactly" crack to make it seem like what you've been
positing all along has finally been iterated by someone with some
credibility.

What's the matter John, are you bitter that several people, who do
understand the theory and practice, have said you are wrong...
