FIELD: measurement equipment.
SUBSTANCE: recirculating conversion method of single time intervals of nanosecond duration to a digital code is based on recirculation in one recirculator of start and stop pulses of initial calibrated duration, which correspond to the beginning and the end of converted time interval, at that, with recirculation period of a stop pulse, initial calibrated duration, which is equal to T. Duration values of start and stop pulses of initial calibrated duration in each recirculation are left unchanged; recirculation period of start pulse of initial calibrated duration is chosen equal to T+τ, where τ - discreteness of conversion; number of recirculations performed with the stop pulse of initial calibrated duration is calculated from the beginning of recirculation and till recirculating start and stop pulses coincide, and digital result of conversion is represented with the counted number of recirculations performed with the stop pulse of the initial calibrated duration.
EFFECT: improving conversion reliability.
