IPC: H04B1/16
Filed: 1994-10-03
Abstract: PURPOSE: To prevent the generation of miscorrection accompanying the correction of time near correct time by correcting only minute data in a clock means at the time of judging the non-coincidence of only minute data by a time lag decision means. CONSTITUTION: A clock function is built in a microcomputer 12, an internal clock is compared with time data in CT data obtained from an RDS data synchronizing/error correcting part 11 and the minutes of the built-in clock are corrected based upon CT data. In this case, the time data of the internal clock are compared with that of local time, and when both the data coincide with each other, the minute data of the internal clock are compared with that of the local time. When both the data are different from each other, the minute data of a clock timer in the internal clock are allowed to coincide with the minutes of the local time. Consequently only the minute data of the clock means are automatically corrected so as to coincide with time data.
