Abstract :
A monolithic CCD adaptive filter chip is described which implements the Widrow-Hoff "clipped-data" LMS adaptive algorithm. The chip can be used as a pre-filter noise canceller, analysis filter, or pre-whitener for a pitch extractor in linear prediction coding (LPC) voice bandwidth reduction systems.
