Abstract
PURPOSE:To attain phase matching immediately even when the phase between broadcast stations is deviated by superimposing a clear pulse onto a synchronizing signal and allowing each broadcast station to match the phase of the synchronizing signal forcibly based on the clear pulse. CONSTITUTION:A synchronizing signal Sd of a signal generator 10 is given to an AM modulation section 24 and to a frequency division section 23 to form a clear pulse to always keep the phase of synchronization constant and a 100Hz clear pulse SCP is generated. The clear pulse SCP is given to the AM modulation section 24, superimposed on the synchronizing signal Sd and the result is sent to broadcast stations 20A', 20B', in which a multiple demodulation section 14 demultiplexes a synchronizing system signal Ss and an AM demodulation section 164 obtains the synchronizing signal Sd and the clear pulse SCP. Then the clear pulse SCP clears the frequency divider 15' forcibly to match the phase of the synchronizing signal Sd.
