摘要： A pulse wave detector for detecting a pulse wave and a pulsimeter using the detector, capable of providing a pulse wave signal having noise components removed appropriately from a pulse waveform and determining the number of pulses with high accuracy on the basis of the pulse wave signal. The pulse wave signal and the pulse rate are delivered in the following way. A pulse wave signal from a pulse wave detection sensor unit (30) is temporarily stored in a buffer (503). When impulse noise detection means (505) detects an impulse noise in the pulse wave signal on the buffer (503), the pass band of a first digital filter (506) describes a mountain shape with its center positioned at the frequency corresponding to the previous pulse rate, and the impulse noise in the pulse wave signal outputted from the buffer (503) is reduced. After the overall noises and the body movement components in the pulse signal are reduced by second and third digital filters (507 and 508), a frequency analysis portion (509) executes frequency analysis and the number of pulses is calculated from this analysis result.

摘要： A pulsometer whose detection result is indicated with high reliability. An SN state detecting means detects the SN state of pulse wave signals (Step S201). The SN state detecting means judges whether the detected SN state is normal or not in accordance with a predetermined threshold (Step S202). If it is judged that the SN state is normal, an indicating means outputs an indication control signal by which a pulse rate is indicated to an indication method switching means (Step S203). On the other hand, if it is judged that the SN state is not normal in the step S202, the indicating means does not indicate the pulse rate and an indication control signal by which no information is indicated at all is outputted to the indication method switching means (Step S204).

摘要： In order to be able to accurately measure pitch both during running and walking, the invention focuses on the fact that the second harmonic of the body movement can be detected at a high level during running and that the third harmonic of the body movement can be detected at a high level during walking, and is designed to be able to calculate pitch regardless of whether or not the user is running or walking, by using a high-level line spectrum appearing in the area that is at or above 100 times/minute, for example, as the reference wave, and by determining whether this reference wave is the second or third harmonic. Whether the reference wave is the second or third harmonic can be determined based on whether or not a high-level signal is present near a frequency that is 1/3 or 2/3 of the frequency of the reference wave, for example; and pitch can be calculated by determining that the reference wave is the second harmonic if no high-level signal is present in the above frequency band.
