\u3cp\u3eA system extracts an ECG signal from a composite signal (308) representing an electric measurement of a living subject. Identification means (304) identify a plurality of temporal segments (309) of the composite signal corresponding to a plurality of predetermined segments (202,204,206) of an ECG complex (208). A template generator (306) generates a plurality of respective template segments (310) corresponding to the respective predetermined segments (202,204,206), wherein a respective template segment is based on a plurality of the corresponding identified temporal segments, the template segments representing extracted portions of the ECG signal. A signal generator (312) combines a plurality of the template segments (310) to obtain an extracted ECG signal (314). The composite signal may comprise a maternal ECG signal and a fetal ECG signal, or the ECG signal and an EMG signal.\u3c/p\u3
