Abstract

PURPOSE:To discriminate an error of receiving time information to prevent the erroneous correction of a slave clock, by adding a parity bit to binary coded time information transmitted from a master clock and by performing parity check at the receiving time. CONSTITUTION:Binary coded time information, to which a one-bit parity is added, from a clock part 3 an an encoder 4 of a master clock 1 is transmitted through a transmission circuit 6, a transmission antenna 7, etc. This information is received by a receiving antenna 9 and a receiving circuit 10 of a slave clock 2 and is detected by a regular pulse detecting circuit 11. This information is subjected to the parity check by a parity check circuit 12; and the time of a clock part 14 is corrected through a correction control circuit 13 only when no bit errors exist in time information, and erroneous correction based on erroneous information due to noise, etc. during transmission is prevented.
