High speed stored product recursive digital filters
Daniel M. Dubois, W.J.D. Steenaart · IEEE Transactions on Circuits and Systems · 1982
A stored product digital filter (SPDF) architecture is developed that will allow for high speed signal processing, for the application of a single address code simultaneously to all product memories, and for the application of either linear binary or nonlinearly coded (PCM) signal codes. The application of this technique will extend real-time digital signal processing capabilities into the megahertz range.
