RE: Absolute Polarity, Asymmetric waveforms and clipping effects

Yes but....
Like with a sine wave, it must exist for a period of time before it represents a single frequency (assuming it has no distortion) and not a bandwidth.
The "flat DC" portion only lasts for a very short time and an FFT of the wave-shape would likewise show a wide bandwidth and not DC.
