Zusammenfassung:The paper considers the possibility of using a wavelet filter in cardiointervalography to isolate heart sounds against the background noise. The filtering conditions and requirements for the signal are discussed. The results of studies of the applicability of various types of wavelets for filtering model and experimental signals are presented and recommendations are given.
