FIELD: physics. ^ SUBSTANCE: alternating odd and even separate measurement intervals with duration equal to Tx+äx and Tx-äx, where Tx is the period of the input signal, äx is the duration of the input signal, are formed. Quantising pulses with repetition period T0 during n measurement intervals Tx are counted. The averaged value of duration of the input time interval over the overall measurement interval is determined using the formula: where n is the even number of periods of the input signal in the overall measurement interval; T0 is the repetition period of the counted pulses; N2j-i and N2j denote the number of quantizing pulses in the j-th odd and even separate measurement interval, respectively. ^ EFFECT: wider range for measuring duration of time intervals while increasing measurement accuracy and simplifying hardware implementation. ^ 2 dwg |
