There is described a signal-controlling apparatus, having signal-processing circuits in each of which a synchronizing operation is improved. The signal-controlling apparatus includes a plurality of signal-processing circuits, each of which includes a clock-generating section to generate a clock pulse signal; a data communication line through which digital data are bilaterally communicated between the plurality of signal-processing circuits; and a reference pulse communication line through which a reference pulse is transmitted from a master signal-processing circuit, being anyone of the plurality of signal-processing circuits, to a slave signal-processing circuit, being another one of the plurality of signal-processing circuits. In the slave signal-processing circuit, the clock-generating section generates the clock pulse signal so as to adjust a phase of the clock pulse signal to that of the digital data, based on a phase of the reference pulse. The reference pulse periodically transmitted at a predetermined time interval. <IMAGE> |
