| Abstract: | Heart sound signals can be used to diagnose some diseases of heart valves andmuscles. The heart sound signal is a kind of nonstationary signals. Since a digital signalprocessing technique, wavelet transform has been reported to be suitable to analyse thenonstationary signals, a method to analyse heart sound signals using wavelet transform isdescribed in this paper. From the experiments of analysis of computer simulated heart soundsignals, it was found that wavelet transform can be used effectively to analyse the heartsound signal so that a new method is provided to diagnose the heart diseases using heartsound signals. |
