<p>Provided are a signal delay device and a signal delay device control method with which it is possible to easily set a degree of delay which is applied to an input signal. A signal delay device which outputs a delay signal whereby a delay is applied to an input signal comprises: a delay means, further comprising a plurality of display units which are serially connected, wherein each delay unit applies a delay to an inputted signal and outputs same; a selection means for outputting the delay signal, further comprising a plurality of selection units which are serially connected and which receive as input the output of one of the plurality of delay units, wherein each selection unit other than the headmost selection unit receives as input the output of the preceding selection unit and outputs either the output from the delay unit or the output from the previous selection unit, depending on the inputted selection signal; a register unit which retains delay setting data which sets the degree of delay of the signal delay device; and a selection signal generation unit which, on the basis of the delay setting data which the register unit retains, generates a selection signal which denotes the selection unit which selects the corresponding display unit output and outputs said selection signal to the selection means.</p> |
