Patent ID: 8391422

Claim:
A time information receiver which receives a standard radio wave containing a time code in which data pulses are arranged at a predetermined period, and analyzes the time code from a demodulated signal of the standard radio wave, the time information receiver comprising: a determining section for determining rising and falling points of the demodulated signal; a time-shift adder for executing, over one second, logical addition of (i) one pulse waveform of the demodulated signal and (ii) a time-shifted pulse waveform obtained by shifting a next pulse waveform of the demodulated signal by a predetermined time, the one pulse waveform and the next pulse waveform being obtained based on a determination of the determining section; and a judger for judging a code type of the time code contained in the received standard radio wave on the basis of whether an addition result of the time-shift adder contains a low-level period or not.
