ABSTRACT:
An analog system (100) of measuring the difference in time of occurrence of events. The method uses two coherent oscillators (110, 116) of the same frequency which start with predetermined phase when each of the events are detected. The phase difference of the oscillators (110, 116) is a measure of the difference in the time of occurrence of the two events.
