Abstract	Phonocardiography is a modern form of auscultation, it consists in the graphical representation of heart sounds. Digital signal processing techniques applied to phonocardiography result in developing a more reliable heart sounds monitoring system in less time and at lower costs. This paper describes the design and implementation of a heart sound monitoring system on Digital Signal Processor board; graphical representation of heart sound is implemented on a MATLAB platform through Real-Time Data Exchange algorithms and two methods to extract the time and frequency characteristics of the heart sounds are presented: short time fourier transform and wavelet transforms. Experimental data is processed comparing the obtained results from both algorithms.
