The technique of analyzing Fetal Heart Rate (FHR) variability has been known to be effective to diagnose the fetal health condition in detail. In order to analyze the FHR variability, it is necessary to develop the method of measuring accurately the FHR, which corresponds to RR-interval in case of ECG, using fetal heart sounds. In this paper, the experimental results of the denoizing the fetal heart sounds obtained by ultrasound cardiograph, using multiresolution analysis method of discrete wavelet transformation, are described, and the effectiveness of the several points which are (1) the level of multiresolution analysis, (2) the sort of mother wavelets, and (3) the change of spectrum by denoizing process, are discussed. |
