1. electric wave calibration clock and watch is characterized in that, these electric wave calibration clock and watch constitute to have:

  • Reception comprises the receiving element of the standard wave of time information;

    Demodulating unit, it carries out demodulation to the standard wave that is received by above-mentioned receiving element, the output restituted signal;

    The waveform judgement unit, its waveform discrimination standard is according to the rules differentiated the waveform of above-mentioned restituted signal, exports the code corresponding with this waveform;

    To be the time information converting unit of time information by the code conversion of above-mentioned waveform judgement unit output;

    AndChange the waveform discrimination standard change unit of above-mentioned waveform discrimination standard.
