ABSTRACT:
Code data indicated by a time code signal is judged according to the kind of a standard frequency broadcast to be received at the time of decoding the time code signal. For example, in the case of receiving a JJY standard frequency broadcast, the time code signal falls at time points t21and t23in a second period T2,and the code data indicated by the time code signal in the second period T2is judged based on the time point t23at which the time code signal falls last between the time points t21and t23. Thereby, even if a lot of noise components are included in a reception signal, the pertinently detection of the time information is enabled.
