FIELD: physics.
SUBSTANCE: proposed group of inventions is distinguished by that, time is measured using a timer whose counter works in continuous mode without interruption. At the end and the beginning of the measured period or at the end and the beginning of the averaging interval, contents of the counter of the timer are stored in registers by capturing, and duration of the period of the measured instantaneous frequency or averaging interval of the averaged frequency is determined from the difference of corresponding codes of the counter of the timer at the end and the beginning of the measured period or averaging interval.
EFFECT: increased accuracy of measuring frequency.
