The Fetal Electrocardiogram (FECG) expresses valuable information about the health status of the mother and baby. An analysis of the complex signal helps experts in making decision during labor. The main interest of FECG analysis is in the field of biomedical applications and clinical diagnosis. Extracting FECG signals is considered a major challenge while the fetus is inside the mother’s uterus. Number of methods are available that can be used to extract FECG from Mothers ECG and detect Fetal heart rate and power in the signals generated by the heart. An ECG signal is recorded by way of putting electrodes on the maternal stomach but the fetal ECG is always masked by maternal ECG and noise. In this research work one of band pass filter is used to get filtered FECG. The original signal is passed through filter which has a frequency of 150 to 160 Hz. Then the filtered signal is analyzed through spectrogram and the power in the signal is extracted that contains P1, P2, Pm amplitude values for Direct1, Abdoment1, Abdomen 2 and Abdomen3 of the ECG signal downloaded from PHYSIONET database. The power in the signal is more for Direct1 signal compared to Abdomen1, Abdomen 2 and Abdomen3 and Abdomen 4.
