Sum a 1 volt peak sinewave with a 0.6 volt dc term and you have a
waveform whose polarity continuously changes but whose average value is
continuous.

Looking at the Fourier terms makes this waveform perfectly clear.
Calling it "AC" or "DC" does not.

"AC" or "DC" are gross and meaningless oversimplifications.

Didn't you just say in your immediately previous post:
----------------------------------------------------------------
""DC" is simply the first (or "offset" term in the Fourier expression
of
any repetitive waveform.

"AC" are all of the remaining components."

Did you intend to offer these descriptions knowing that they were
"gross and meaningless oversimplifications"? Why bother in that case?
