Abstract

A large number of papers usually use the so-called actually detected fetal ECG data in DAISY database to test their fetal ECG extraction algorithms. However, we found that the fetal ECG data in DAISY database are not sure to be the real measured data from the abdominal surface. The reasons are: (1) In the comparative waveform analysis of the data´s different channel signals, it is noticed that there is nearly no delay between two corresponding R peaks of different channel signals, which is not reasonable, (2) In frequency domain, we cannot see the characteristics of 50Hz power frequency interference in the spectrum for an actually measured signal.
