Analysis of the bit-level operations involved in the convolutions realizing recursive digital filters leads to hardware designs of such filters based on the operation of counting. Various designs realizing both the canonic and "direct" forms are presented with particular emphasis on low-cost low-speed high-flexibility machines.
Canonic digital filters, digital filters, "direct" digital filters, hardware digital filters, negative radix application, real-time digital filters.
