Abstract:
A time information receiver including a reception unit for receiving and demodulating a standard radio wave containing a time code in which data pulses are arranged at a predetermined period; an analyzer for analyzing the time code from a demodulated signal obtained by demodulating the standard radio wave; a time-shift adder for executing an addition processing of adding a pulse waveform of the demodulated signal and a pulse waveform of a signal obtained by shifting the demodulated signal by a predetermined time; and a judger for judging a code type of the time code contained in the received standard radio wave on the basis of a addition result of the time-shift adder.
