Foetal ECG signal detected via electrodes placed on mother’s abdomen

1.	Foetal ECG signal detected via electrodes placed on mother’s abdomen is complex and requires attenuation of maternal signals for obtaining FHR.(a) True(b) FalseI had been asked this question by my school principal while I was bunking the class.Origin of the question is Measurement of Hearing in division Audiometry of Biomedical Instrumentation
Answer» CORRECT answer is (a) True The best explanation: It is True. Foetal ECG SIGNAL detected via electrodes placed on the mother’s abdomen is complex and requires attenuation of maternal signals for obtaining FHR. Also, due to the overlapping of the foetal ECG with the maternal ECG, about 20% to 50% of the expected PULSES may be MISSING.
