Abstract
A digital limiter for processing a digital video signal includes a limiter stage whose output is subtracted from the input to the stage in a subtracting stage. The resulting difference signal is accumulated by means of an accumulating device. The accumulated signal is added to the digital video signal to be processed. The accumulator provides a memory function for the signal component clipped in the limiter. It also includes a leakage device, so that the accumulated signal can decrease again after the start of limiting action.
