This paper presents a new algorithm to extract

the fetal ECG from an ECG recorded on the

mother’s abdomen. The algorithm consists of

two steps: first, ECG of fetus is extracted from

the original signal using a two-level wavelet

transform. We use Daubechie wavelet transform,

which is similar in shape to heart beat wave. The

resulted signal is then low-pass filtered using the

Savitzky-Golay smoothing filter to attenuate the

effect of noise. The filtered signal is considered

as the fetal ECG. The algorithm was applied on

both synthetic and real ECG signals. The results

in this paper show that the proposed algorithm

has promising performance.
