Patent ID: 8089918

Claim:
A time information receiver which receives a time code in which a plurality of different data pulses identified by width or pattern are arranged in respective unit periods of the time code, the time information receiver comprising: a sampler that samples a detected signal of the time code at intervals of time shorter than the unit period with respect to a synchronization point in the unit period; calculating means for calculating a respective correlation value for each of the plurality of data pulses of the detected signal based on the sampled data obtained from the sampler; and a determiner that determines a type of data pulse of the detected signal corresponding to a maximum correlation value among the correlation values calculated by the calculating means; wherein when one of the plurality of data pulses has an ideal pulse waveform, the calculating means takes, as the correlation value for the one of the data pulses, a difference between a single sampled value, or a composite value of a plurality of sampled data values, of the one of data pulses immediately before a time point where the one of data pulses rises or falls and a single sampled value, or a composite value of a plurality of sampled data values, of the one of data pulses immediately after the time point.
