MULTICHANNEL DIGITAL FILTER Russian patent published in 1995 - IPC

FIELD: radio systems. SUBSTANCE: digital filter has N channels set up of series-connected input register and comparator, series-connected reference train shaper and output register, and also threshold unit, NOT gate, two RS flip-flops, JK flip-flop, and OR gate. Control device functions to synchronize filter operation. Reference train shaper is essentially assembly of series-connected reference train generator and reversing counted. NOT gate, RS flip-flop, JK flip-flop, and OR gate introduced in filter and specific design of shaper ensure filtering in much narrower range determined by input code. EFFECT: improved speed of filter. 2 dwg
