GATED-CLOCK TIME MEASUREMENT APPARATUS INCLUDING GRANULARITY ERROR ELIMINATION

摘要

A precise measure of the time interval between the occurrence of first and second events is obtained by utilizing gated-clock time interval measurement apparatus. A plurality of clock pulses occurring during the interval between the events is counted. Errors in the time interval measurement are minimized by obtaining a measure of an interval between the first event and the first counted clock pulse and by obtaining a measure of an interval between the last counted clock pulse and the second event. Analog signals representative of the error intervals and the clock pulse count are combined to yield the desired time interval measurement.
