It is reported that the measurement error of the fetal heart rate variability, which is obtained by a cardiotocograph with a Doppler ultrasonics signal, is large even if the auto-correlation technique is used. Simulations are performed to estimate the effect of the measurement error on the spectral analysis. The following two respects are confirmed: (1) when the error is distributed uniformly from -15 msec to +15 msec, the noise level of the spectrum is -12 dB, and (2) the noise level is not… CONTINUE READING
