Main theoretical basis of biosignals modeling

The phonocardiosignal (PCS) synchronously registered with electrocardiosignal simulation model was de- veloped in this work using the methods as: the real signal envelope calculation, the real PCS signal approximation using the piecewise, bandpass filtration for “frequency-filling vector” and band-limited white noise calculation. The software in the MATLAB environment for the PCS simulation as the means of heart pathology detection algorithms verification in cardiac diagnostic systems was developed.Palaniza Y.B.
