摘要
A signal extracting apparatus is provided based on independent component analysis with reference for a single measured signal as a signal processing technique that allows stable and quick extraction of a target signal from single measured signal even in a high-noise environment with a high noise ratio against a target signal to be extracted. The signal extracting apparatus includes: a single-signal measuring unit to measure a measured signal as a single time-series signal containing a target signal obtained by measurement by a single channel; a reference signal creating unit (2) to create a reference signal provided with timing-axis information based on the time-series signal obtained by the single-signal measuring unit; and a main processing unit (5) to perform independent component analysis with reference for a single measured signal by capturing the reference signal obtained by the reference signal creating unit (2) and providing the timing-axis information for an algorithm in a reference system to extract an independent component.
