PROBLEM TO BE SOLVED: To improve the accuracy of the state values calculated as they are from the specified objective spectrum of the spectra after a frequency analysis by subjecting these state values to correction of the quantity obtd. by comparison of the intensity in the direction of the increase/decrease obtd. from the result of comparison of the intensity of the two adjacent spectra. SOLUTION: A portable pulse wave measuring instrument 1 consists of an instrument body 10 of a wristwatch type and a sensor unit 30 for brain wave detection connected thereto and determines the change in the pulse rate, etc., in accordance with the measured brain wave signals. The change, etc., are displayed on a liquid crystal display device 13. The frequency analysis relating to the brain wave signals is effected and the objective spectrum is specified from the spectrum groups discretely obtd. at the intervals corresponding to the resolution thereof. The state values of the pulse rate, pitch, etc., are determined in accordance with the frequency of the objective spectrum. At this time, the intensity of the two adjacent spectra appearing on both sides of the objective spectrum and the intensity of the objective spectrum are compared and the state values are corrected by the quantity obtd. by the comparison. |
