Efficient Computation of Phonocardiographic Signal Analysis with Hardware Implementation

A prototype of a simple and non-invasive system to remotely monitor of the real-time heart rate of patients or individuals based on phonocardiography, the study of heart sounds has been developed. This system consists of five modules. The first module, namely the front-end modules is used to acquire and capture heart sound signals. This article presents a real time system for the heart auscultation monitoring and hearing. The system design comprises of a Phonocardiographic preamplifier circuit. The Phonocardiogram signal from there – amplifier circuits acquired and subjected to various signal processing techniques. Frequency analysis and component analysis are performed to identify the normal and pathological heart and sound patterns. To study the performance of the system, the analysis of heart sound patterns for various diseases were conducted.
