The visual analysis of fetal heart rate (FHR) traces largely depends on the expertise and experience of the clinician involved.Various algorithms of autoregressive (AR) recursive identification make it possible to evaluate power spectral distribution in correspondence with each sample of a time series, and time-variant spectral parameters can be calculated through the evaluation of the pole positions in the complex z-plane.neural classifier system preliminary feature extraction and selection process using time-frequency representation of heart rate variability (HRV) signal is presented.
