Zusammenfassung:The abdominal signal recorded on the abdomen of a pregnant woman allows the fECG extraction for a further analysis. The main problem when using the ADSs is that they contain not only the signals of interest but also some disturbing signals that influence the fECG extraction methods. This study proposes an adaptive algorithm that removes the main PLI frequency and its harmonics from the real and simulated abdominal signals. The algorithm is quite stable and preserve the fECG morphology.
