ABSTRACT:
Low pass sampled data filters tend to produce pre- and post- over/undershoots in the output signal in response to input signal transitions. These over/undershoots or sequence of artifacts are eliminated in the present system by the following method. The input signal is monitored for transitions exceeding an amplitude which tends to generate objectionable artifacts. The values of such transitions are stored and applied to a plurality of weighting circuits to generate a plurality of signal values corresponding to respective ones of the sequence of artifacts. The weighted samples are selectively combined with the filter output samples in time correspondence with the occurrence of the output artifacts to cancel the effects of the artifacts.
