PURPOSE: A delay correction circuit is provided to perform the predetermined delay period after a timing signal is detected and correct the delay period in case of inaccurate correction of the timing signal. CONSTITUTION: A delay correction circuit includes a source (15) of a clock signal and a source (5) of a timing signal asynchronous with the clock signal. A timing signal detector (10) is responsive to the clock signal and the timing signal, and is properly operative only when the timing signal is stable for a predetermined time period around the clock signal. A control circuit (70) conditions utilization circuitry (80) to operate after a delay time after the timing signal is detected. Adjusting circuitry (10, 20, 30, 40, 50, 60) conditions the control circuit (70) to adjust the delay time if the timing signal was not stable within the predetermined time period.
