| Abstract: | The weighted average tracking algorithm (WATA)is applied to heart sounds processing. First the influence caused by the signal-dead-period noise is analyzed by using the simulation signal and the method to eliminate it is presented. Then the WATA is applied to heart sounds processing. The application of the WATA may promisingly provide comprehensive and quantized information for heart disease diagnosis. |
