摘要
The fetal heart potential signal extraction program implements on a computer: a selection function that selects, from among multiple biopotential signals, a prescribed biopotential signal wherein the maternal heart potential signal component is large; an independent component analysis function that performs independent component analysis on the multiple biopotential signals; a periodic signal-detecting function that detects, in the biopotential signal selected by the selection function and each output signal from the independent component analysis, signals having periodic peaks as peak timing signals; an output signal selection function that uses the peak timing signal of the biopotential signal selected by the selection function as the reference input, a peak timing signal from among the output signals of the independent component analysis as a comparative input, and selects an output signal that has a peak timing differing from the peak timing signal of the biopotential signal; and a function that outputs the selected output signal.
