ABSTRACT:
A digital peaking circuit for processing digital luminance signal in a video processing system combines parallel paths of delay elements and summing circuits to produce the desired luminance response curve with minimum hardware. Only one scaling circuit is required to achieve the desired frequency response characteristic and one multiplier is included to render the peaking circuit adaptive.
