Abstract

A device for measuring the duration of a time interval between an interval start signal (D) and an interval end signal (F). The device includes a digital circuit having first and second clocks (C1, C2) for counting the number of clock pulses between the interval start signal (D) and the interval end signal (F), an analog circuit for measuring the time separating the interval start signal (D) from a clock pulse following the interval start signal, and also for measuring the time separating the interval end signal (F) and a clock pulse following the interval end signal, and a processing circuit for determining the duration of the time interval based upon data supplied the digital circuit and data supplied by the analog circuit (previously converted into digital data). Particular utility for the present invention is found in the area of robotics.
