PURPOSE:To increase the number of transmitted information words independently of a prescribed period for synchronism correction, by providing a circuit generating a synchronizing reference pulse at a prescribed period independently of a set address of an address setter and interrupting a synchronizing signal when this pulse is generated. CONSTITUTION:Each data inputted to data input devices 11-1-11-n is scanned at each transmission word from an address setter 12 accompanied with the number of pulses corresponding to one word of a clock 10 and an address to an address data output device 26 is given sequentially. A prescribed code is given to a data provided with the address at a parallel serial converter 14 and outputted to a modulator 15. A synchronizing reference circuit 16 outputs a synchronizing reference pulse to a synchronizing signal circuit 13 every time the number of pulses of the clock 10 corresponds to 32-word. When the circuit 13 receives the synchronizing reference pulse, a synchronizing word is formed and it is interrupted to a parallel serial converter 14 to an output of the address setter 12. |
