発明の名称 （英語）	SIGNAL EXTRACTING APPARATUS
発明の概要（英語）	Provided is a signal extracting apparatus based on a single-measurement-signal reference-system independent-component analyzing method as a signal processing technique that, even in a high-noise environment where the ratio of noise to a target signal to be extracted is high, can stably and quickly extract the target signal from a single measurement signal. The signal extracting apparatus comprises: a single-signal measuring unit for measuring a measurement signal that is a single time sequence signal obtained by a measurement, which uses a single channel, and including a target signal; a reference signal creating unit (2) for creating a reference signal to which information of time axis is given based on the time sequence signal obtained by the single-signal input unit; and a main calculating unit (5) that is operative to take in the reference signal obtained by the reference signal creating unit (2) and to perform a single-measurement-signal reference-system independent-component analysis in which the information of time axis is given to an algorithm in the reference system, thereby extracting independent components.
