Abstract

PURPOSE:To ensure the synchronism, by obtaining the simultaneousness of digital information received at a reception station, through taking the standard electromagnetic waves as the sample start signal of each transmission station. CONSTITUTION:A receiver 18 receives the standard electromagnetic waves from a standard wave reception antenna 17, and this is given to a time device 19 as the standard one second pulse. The time device 19 compares this pulse with the one second pulse of the self-running clock given by itself to make correct one second pulse. Thus, the minimum time of sample period formed from the same clock is corrected, this minimum unit time is fed to an interval production circuit 20, where the sample period is counted to transmit signal to the sample circuit 6 at the start of sample and to start the sample. The synchronism for the sample start time is made possible, by performing the said operation at other transmitting stations.
