Abstract: Foetal heart sound can be extracted from maternal abdominal surface; the technique is also known as foetal Phonocardiography (fPCG). This work investigates the analysis of foetal heart sound in time domain using a novel signal processing algorithm. An innovative approach is presented for the foetal heart sound acquisition, processing, and time domain representation, which can be used in a portable foetal home monitoring applications. The system has been tested for various real and simulated foetal heart sound signals. The outcome of the process is segmented foetal phonocardiogram along with Foetal Heart Rate (FHR) parameters viz., average FHR, standard deviation of FHR and finally the FHR trace.
