摘要： In a synchronous detection method, an input signal is averaged over at least first and second phase ranges of a target carrier wave within each period thereof to obtain at least first and second moving average values of the input signal within the at least first and second phase ranges, respectively. The first phase range corresponds to a positively oscillating phase range of the target carrier wave, and the second phase range corresponds to a negatively oscillating phase range thereof. A difference between the first and second moving averages is calculated as a detection result of the target carrier wave.

摘要： In a positional information detecting device, a tone-burst signal propagating unit causes a tone-burst signal to propagate through a path. The tone-burst signal is composed of a continuous wave train, the continuous wave train including a plurality of cycles of a constant frequency. A detecting unit detects, at a predetermined position in the path, the tone-burst signal propagating through the path every one cycle of the tone-burst signal to measure a propagation delay time based on the detected signal. The propagation delay time represents a period for which the tone-burst signal has propagated through the path. A phase obtaining unit obtains a phase of the detected signal. A positional information obtaining unit obtains positional information associated with the predetermined position based on the measured propagation delay time and the obtained phase of the detected signal.

摘要： In a radio-controlled device for measuring time, a demodulating unit demodulates the time information from the received electric signal based on amplitude information of the target radio wave. The amplitude information is obtained from in-phase and quadrature-phase components of the target radio wave. A phase calculator calculates phase data associated with a phase of the target radio wave based on the in-phase and quadrature-phase components. A variability calculator calculates a variability of the phase data of the target radio wave relative to a reference phase. The reference phase changes at a constant rate in time according to a frequency error. The frequency error is contained in the reference signal relative to a frequency of the target carrier wave. A reception determining unit determines whether reception of the radio-controlled device is good based on the calculated variability.
