Abstract—Phonocardiogram is one of the most unstable signals; therefore phonocardiogram is included of frequency and timing information. Within present study we obtained vast features through STFT and Wavelet algorithm. Our main focus is on signals analysis which shows Aortic Insufficiency diagnosis, then utilized fuzzy logic and neural network to compare two methods.

Index Terms—STFT, wavelet algorithm, fuzzy logic, neural network.
