Abstract:
A time signal repeater which relays a radio signal including a time code for a radio correction clock receiving a standard time radio signal to correct the time, comprising:an antenna portion capable of setting a plurality of resonance frequencies and receiving the standard time radio signal by a set resonance frequency,an oscillating circuit for outputting a signal having a frequency of the received standard time radio signal and synchronized with the standard time radio signal received by the antenna portion,at least one frequency conversion circuit for converting the frequency of the output signal of the oscillating circuit,a receiving circuit for receiving as input the standard time radio signal received by the antenna portion and correcting the time of an internal clock according to the time code included in the received radio signal,a transmission circuit for generating a time radio signal including a time code based on the internal clock based on the output signal of the oscillating circuit or the signal converted in frequency by the frequency conversion circuit at the time of transmission, anda selecting circuit for receiving as input the output signal of the oscillating circuit or the signal converted in frequency by the frequency conversion circuit to the transmission circuit.
