発明の名称 (英語) SIGNAL NOISE ELIMINATOR AND METHOD AND PROGRAM THEREFOR 新技術説明会
発明の概要(英語) Provided is a signal noise eliminator which is capable of reliably eliminating a noise signal while leaving a periodic signal and which, for example, measures a signal in a home or out of doors by minimizing load on the human body. This signal noise eliminator comprises: a peak detection unit (21) which detects a waveform peak of an input process signal; a first resampling unit (24) which resamples the number of detection samples between each of the detected peaks to the number of reference samples; an orthogonal transformation unit (25) which performs orthogonal transformation to the resampled process signal; a filtering unit (26) which extracts, from frequency data after the orthogonal transformation, at least a fundamental frequency component which is a frequency component of a fundamental wave and a harmonic component which is a frequency component of a harmonic wave; an inverse orthogonal transformation unit (27) which performs inverse orthogonal transformation on filtered frequency data; and a second resampling unit (28) which resamples the process signal that is obtained after the inverse orthogonal transformation to the number of detection samples for each peak detected at the peak detection unit (21).
