Abstract

A time duration is measured precisely and with high resolution by making three time measurements as shown in FIG. 5. The time difference tA between the leading edge of a start signal and the next following leading edge of a constant frequency time base signal is measured. The number "n" of the following leading edges is then counted including the leading edge of the time base signal following a stop signal. The number n is multiplied by the period TQ of the time signal. The time difference tE between the leading edge of the stop signal and the next following leading edge of the time base signal is measured. The real time difference DELTA t is then calculated as follows DELTA t=tA+nxTQ-tE. A three part real time measurement is performed to correct the calculated result for drift and aging. Calibration measurements are made and the respective calibration factors are used in calculating the final results. The respective circuit arrangement includes a start channel, a stop channel, and the corresponding supporting circuits.
