<P>PROBLEM TO BE SOLVED: To identify appropriate synchronizing signal from an the edge time of day of time information signal, even if the receiving signal is faint or the receiving signal is overlapped with noise. <P>SOLUTION: The time information receiving device performing time adjustment, in response to radio wave signal of the above standard time includes a receiving circuit receiving the above standard time radio wave signal to derive time information through signal processing of the received signal concerned; a plurality of data acquisition circuits bringing in wave shape edge of the above time information derived from the above receiving circuit; a plurality of cycle determination circuits prepared corresponding to the data acquisition circuits, respectively, to determine the cycle from time data of the above edge supplied from each of the above data acquisition circuits; and a synchronous processing circuit searching synchronizing signal from cycle data determined from a plurality of the cycle determination circuits, to obtain an appropriate synchronizing signal of TCO signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
