A standard time and frequency signal receiver receives a time code in which a plurality of data pulses “1”, “0” and “P” which are identified by width are arranged one in a respective one of unit periods of the standard signal. An amplitude of a detected signal of the time code is sampled with respect to a seconds synchronization point in a unit period. Then, correlation values F1, F0 and FP for the data pulses “P”, “1” and “0”, respectively, are calculated based on the sampled values. These correlation values F1, F0 and FP are then compared to determine the data pulse received. Even when the time code contains a considerable noise, which of the “1”, “0” and “P” signals was received is determined accurately, thereby achieving the reception of the time code with a reduced error. |
