Either that or we are back to Don Lancaster's correct statement
that they are meaningless terms anyway. They certainly are if
that is the way they are defined!

Don first said:
---------------------------------------
'"DC" is simply the first (or "offset" term in the Fourier expression
of
any repetitive waveform.

"AC" are all of the remaining components.'
----------------------------------------

Then he said:
----------------------------------------
'"AC" or "DC" are gross and meaningless oversimplifications.'
----------------------------------------

Which are we to believe?
