DIGITAL LIMITING CIRCUIT

摘要

A digital limiter for limiting the amplitude of a digital video sigal in which the first and last of data which exceed the range between lower and upper limit levels are replaced respectively with an average value of the data preceding the first over data and the upper or lower limit level data and an average value of data following the last over data and the upper or lower limit level data to thereby enable a good soft-limit operation without damaging the linearity of the video signal.
