The Analysis of Heart Sounds and a Pocket Computer Application via Discrete Fourier Transform

Abstract

In this study, the heart sounds achieved through a stethoscope were initially computed, and they were subjected to Discrete Fourier Transform (DFT) and next the graphics and the frequency spectrum in the time domain that belonged to the heart sounds were drawn on the pocket computer. Thus, frequency spectrum of normal and abnormal heart sounds was obtained via DFT, so it was aimed to prepare the physicians with some more data in the course of auscultation.
