摘要：Heart sounds interfere with lung sounds in a way that hampers the potential of respiratory sound analysis in terms of diagnosis of respiratory illness. This paper implements a VI for Heart Sound (HS) cancellation from Lung Sound (LS) records using the Advanced Signal Processing Toolkit of Lab VIEW 8.2. The method uses the multiresolution analysis of the wavelet approximation coefficients of the original signal to detect HS-included segments. Once the HS segments are identified, the method removes them from the wavelet coefficients and estimates the created gaps by using TSA ARMA modeling and prediction.
