Identifikasi Isyarat Suara Murmur Jantung Menggunakan Transformasi Forier Cepat Berbasis Jaringan Syaraf Tiruan
Journal Title: Jurnal Ecotipe (Electronic, Control, Telecommunication, Information, and Power Engineering) - Year 2014, Vol 1, Issue 1
Abstract
This research was to explore the merit of signal processing scheme in solving the identification problems of heart murmurs signal utilizing the available data from a number of Indonesia heart patients. The signal processings were based on an Artificial Neural Network (ANN) method preceded by the Fast Fourier Transform (FFT) analysis and directed to nine known classes of murmurs, namely the stenosis aorta valve,defect septum atrium, regurgitation mitral, defect septum ventricle, click-mid systolic, regurgitation stenosis aorta, presistolic, stenosis mitral, and ductusarteriosus paten ones. The ANN weight vectors were grouped according to their clustering patterns which represent their respective specific features, based on the corresponding training data samples. The 78.5% success of identification on other data samples is encouraging. The research resorted mainly to the available MATLAB software tools.
