<p>PURPOSE:To adjust the timing of the control system of a computer system, etc., by determining a suitable output terminal for obtaining a specific delay time among respective delay times of output terminals of a delay circuit which differ in delay time. CONSTITUTION:A measurement signal generating circuit 14 is actuated when necessary to send out an 'on' signal to a signal line 18 for a certain time. Consequently, when output lines 12-1-12-7 of the delay circuit 11 to which the signal A of a signal line 10 is inputted turn on, a latch circuit 15 sets a latch corresponding to the output line on. A processor 16 calculates the man delay time of the respective output lines 12-1-12-7 from on/off states of latches and the prescribed 'on' time of the on signal of the signal line 18 and compares the mean delay time with a predetermined prescribed delay time to determine an output line through which an optimum delay time is obtained, thereby setting a selecting circuit 13 so that the output line is selected.</p> |
