A new approach alternative to cardiotocographic conventional fetal monitoring is presented. It relies upon analysis of bioelectrical signals recorded from maternal abdominal wall. Due to strong interferences present in abdominal signal advanced methods of signal processing have been developed to extract fetal electrocardiogram and uterine electrical activity signal. The described system allows replacement of more expensive cardiotocographic instrumentation based on ultrasound Doppler method and ensures the higher diagnostic capacity at the same time.
