Abstract
A method and apparatus for measuring time intervals between electrical signals. A coincidence detection circuit is adapted to detect coincidence or near coincidence of two signals and to provide for selection from a plurality of predetermined delays to remove the coincidence. If the two input signals are periodic and have the same frequency, the apparatus also provides a signal from which both the time delay between the signals and the period of the signals may be determined at substantially the same point in time.
