Title:
生体信号解析装置およびその制御方法
Document Type and Number:
Japanese Patent JP7278102
Kind Code:
B2
Abstract:
To provide a biological signal analysis apparatus capable of extracting the basic frequency component of a pulse wave signal without obtaining a pulse rate, and a control method of the apparatus.SOLUTION: The apparatus obtains a first pulse wave signal based on variation in the light volume of reflectance or transmitted light of light of a first wavelength applied to a biological tissue. A signal processing unit 130 uses an adaptive bandpass filter 133 using an adaptive algorithm estimating a basic frequency, extracts the component of the basic frequency from the first pulse wave signal, and outputs the component.SELECTED DRAWING: Figure 2
