Distinguish between Maternal and Fetal ECG Signals

Active research has been done to economically obtain nearly perfect fetal and maternal ECG signals out of a feto-maternal ECG (F/MECG) complex. Researchers gathered multiple techniques to display these signals free of noise, interference and artifacts. The F/MECG complex is a mix of many myographic signals and noise which makes the separation difficult. T he o bjective o f this p aper i s t o a nalyze t he popular procedures used for achieving the goal of representing individual and noise clean ECG signals. It gives a summary of the study on different methods to separate maternal ECG and fetal ECG from F/MECG mix in the mother's abdomen.The paper also incorporates another simple technique of using a moving average filter to attain two signals independently. The study suggests that close to perfect results can be achieved using a simple method.
