PURPOSE:To set a delay time without causing a change in the delay time setting of other channels by making cascade connection by plural delaying devices having delay output and changing the delay data of other channels complementally by an arithmetic means at the time of obtaining a delay output for long time. CONSTITUTION:An Ach delaying device 11, a B1ch delaying device 15 and a B2ch delaying device 16 execute respectively delaying operations by delay data for each ch calculated by an arithmetic means 21 and outputted by an outputting means 23. When the final delaying output time of the B1ch is T'B1 and the final delaying output time of B2ch is T'B2, T'B1=TB1 + TA, T'B2=TB2 + TA are satisfied, when it is desired to make the delay time of T'B1 more than Tmax, it is necessary to change TA. When the change of TA is ATA and if TB2>, the delay time of T' does not change by decreasing ATA from TB2, by the increase of ATA in T'B1. |
