Abstract
A waveform estimation device includes: tracking filter processing unitsandthat execute tracking filter processing on observation values using tracking filters having different drive noises; and a filter output selection unitthat selects a regular waveform component predicted by the tracking filter processing unit, in an irregular section, and selects a regular waveform component predicted by the tracking filter processing unit, in a regular section. A residual processing unitcalculates a residual between observation values extracted by an observation value extraction unit, and a regular waveform component selected by the filter output selection unit. An irregular waveform detection unitdetermines whether the residual is an irregular waveform component.
