Fetal cardiac potential signal extraction program, fetal cardiac potential signal discriminating apparatus and pregnant women watching system using the same

摘要

A fetal cardiac potential signal extraction program, from the biopotential signals, a plurality of selection function for selecting the biopotential signal given large component of maternal cardiac potential signal, the independent component analysis on the biopotential signals of multiple and independent component analysis function of performing, for each output signal of the Independent Component Analysis biopotential signals selected by the selection function, and the periodic signal detecting function for detecting a peak timing signal, a signal having a periodic peaks and the the reference input of the peak timing signals biopotential signal selection function has been selected, the comparison input peak timing signal of the output signal of the independent component analysis, an output signal as a peak timing different from the peak timing signal of the biopotential signal It is implemented on a computer and output signal selection function of selecting, a function of outputting an output signal that is selected.
