摘要: An overview is given of the FEMME-project (Fetal Electrocardiogram Measuring Method and Equipment). The project started in 1981 close to producing a prototype personal computer-based system. This records simultaneously number cutaneous potential signals derives from this set one or more maternal electrocardiogram-free fetal heart signals, by combining linearly recorded signals. on-line adaptive algorithm based on Singular Value Decomposition (SVD) has been designed compute coefficients these linear combinations. will be implemented DSP board that can plugged into real-time recording system very useful studies electrocardiogram during pregnancy but also all other such as rate variability, movements, etc., where precise trigger electrical signal required.
