Cardiac auscultation is a primary diagnostic tool in the detection and management of cardiac disease. It is a noninvasive technique of listening to sounds produced by heart. In order to make the system reliable and proceed to make real-time operation, a new method is developed and evaluated. A novel framework for heart sound analysis based on discrete wavelet transform (DWT) decomposition and its implementation in VHDL is presented in this paper. Autocorrelation of the average Shannon energy envelope is extracted as feature from the sub-band coefficients of the heart signal with the DWT. Simulation is done in both MATLAB and Xilinx ISE 12.1 with the help of ModelSim simulator. The proposed method is evaluated on publically available datasets published in the PASCAL Classifying Heart Sounds Challenge.
