RING COUNTER Russian patent published in 2001 - IPC

FIELD: pulse equipment, various digital devices operating under effect of interference. SUBSTANCE: ring counter has analyzer 1 of state of digits of counter, first 12 and second 13 inverters, first 14, second 15, third 16, fourth 17 and fifth 18 NOT-OR gates, RC element 19 of recording, group of RC elements 20-23 of recording, input bus 24 and reset bus 25. Ring counter is supplemented with OR- ELSE gate 2, group of OR-ELSE gates 3-6, majority gate 7, group of majority gates 8-11. Technical objective of invention lies in simplification of ring counter with even number of digits by reduction of number of groups of logic elements carrying n elements thanks to change of recording of new states of counter in RC elements of digits and of results of analysis of even state in RC element. EFFECT: simplification of ring counter.
