Abstract
A detecting instrument for detecting time difference between input times of two signals through the use of correlation function is disclosed. The instrument includes a digital circuit for repetitive computing of the correlation function between the two input signals and an analog circuit for detecting the phase of the fundamental frequency component of the repeated correlation function provided by the digital circuit.
