FIELD: measurement technology. SUBSTANCE: invention refers to instrumentation engineering and is intended to measure frequency of pulse signals. Technical result of invention takes in given meter the form of coding of numbers with floating point which maintains word size of meter constant practically in unlimited measurement range. Insertion of additional binary counter allows modulus of order of code of measured frequency to be formed and sign of order to be determined. Change-over switch ensures correct functioning of this counter in case of change of sign of order. Insertion of flip-flop gives possibility to fix sign of order. EFFECT: expanded application field. 1 dwg
