摘要

A method for extracting a signal of interest from a signal generated from at least one subject, comprises the steps of (A) obtaining a time-series signal generated from the subject as a data group consisting of a plurality of pieces of data, (B) obtaining a plurality of extracted data groups from the data group, wherein each extracted data group comprises a predetermined number of pieces of data selected from the data group, (C) calculating standard deviations of the plurality of extracted data groups to obtain a standard deviation group, and (D) referencing each standard deviation included in the standard deviation group and selecting the signal of interest.
