CLIPPING |
---|
An electronic process for limiting the amplitude of video or audio signals. Sometimes, clipping is performed prior to Modulation and sometimes to limit signal level, so that it will not exceed a predetermined, allowed level. In video, the term SOFT clipping is used when the luminance signal is limited, and HARD clipping is used when both luminance and chrominance signals are limited. Clipping a signal can distort it, resulting in additional, unwanted harmonics. |
