Total and utter horse****.

"DC" is simply the first (or "offset" term in the Fourier expression of
any repetitive waveform.

DC, of course, cannot exist at all ever. Because it would have to be
unvarying through infinite time.


So, the first Fourier term is always zero. Got it.




Damn, this thread will hit 200 posts soon. The less the content, the
bigger the thread.

Amazing isn't it? We're actually witnessing a dispute over what AC and DC are? And
whether such things even exist?


There seems to be a consensus that, since no signal is absolutely
stable with time, then DC must not exist. That does simplify life.
