ABSTRACT:
On a line scanned video display, the frequency of an artifact producing signal within the video passband is selected to be an odd harmonic of one half the horizontal line scan frequency so that adjacent scan lines of the artifact are 180 degrees out of phase with each other. Thus, the artifact is rendered largely visually canceled when viewed due to the integrating characteristics of the eye of the viewer, even though the artifact is still there.
