FIELD: data processing.
SUBSTANCE: invention relates to means of detecting a bit pattern. Device comprises: first RS trigger, second delay trigger, first OR element, first AND element, first counter of the number of overlapping patterns CTS, second counter of the number of non-overlapping patterns CTN, second AND element, second OR element, third subtracting counter of bits of pattern CTK, fourth counter of intervals CTI, output buffer OB, multiplexer MUX, third element, third trigger of unit bits of interval TRI, input data shift register RD, first and second AND groups of AND elements, decoder DC, group of OR elements, comparator COMP.
EFFECT: detecting overlapping and non-overlapping patterns of a given bit depth, determining their number, as well as counting the number of bits in intervals between patterns and identifying single bits between patterns.
