PROBLEM TO BE SOLVED: To solve the problems that a digital circuit increases in size, and costs increase when all signal processing are performed by a logic IC, and power consumption increases by leak current, etc. in a radio clock which receives radio signals such as a GPS signal and a standard radio wave signal.SOLUTION: A radio clock is constituted by including: a receiving circuit 102 which receives radio signals to output receiving signals; a decoder 103 in which the receiving signals are input, and which performs various digital processing to output digital data; and control means (CPU) 104 in which the digital data is input to be processed as various kinds of information data, and so that the decoder 103 can be further changed into configurations optimal to processing at the respective states for every stage of the digital processing by control from the control means (CPU) 104. |
