PROBLEM TO BE SOLVED: To provide a biological signal estimation device that derives a frequency of a waveform of potential of an electric signal generated in a living body in a shorter time than in a case of using fast Fourier transformation.SOLUTION: A biological signal estimation device 10 includes: potential measurement means 11 for intermittently measuring a potential of an electric signal generated in a living body S and frequency calculation means 12 for calculating a frequency of a waveform formed by change of multiple measurement values with respect to a temporal axis by using a hyperfunction with a measurement value group formed of multiple measurement values obtained by the potential measurement means 11 during measurement in a predetermined time as a target. Calculation of frequencies is simplified compared with a case of using fast Fourier transformation.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】生体で生じる電気信号の電位の波形の周波数を、高速フーリエ変換を用いるより、短い時間で導出する生体信号推定装置を提供する。【解決手段】生体信号推定装置10は、生体Sで生じる電気信号の電位を間欠的に計測する電位計測手段11と、電位計測手段11が所定時間内の計測で得た複数の計測値からなる計測値群を対象に、複数の計測値の時間軸に対する変化からなる波形の周波数を、超関数を用いて算出する周波数算出手段12とを備えて、高速フーリエ変換を利用するのに比べ、周波数の算出の簡素化を図る。【選択図】図1
