SIGNAL PROCESSING APPARATUS AND COMPUTER PROGRAM PRODUCT FOR PHONOCARDIOGRAM SIGNAL

摘要

A signal processing apparatus includes a phonocardiogram interface configured to receive a phonocardiogram signal captured according to a first set of capturing properties, a processor configured to analyze the phonocardiogram signal to determine an analysis result for the phonocardiogram signal and a confidence value of the determined analysis result, and a flow control configured to determine, whether a subsequent capture of the phonocardiogram signal according to a second set of capturing properties is likely to improve an accuracy of the determined analysis result. If applicable, the flow control coordinates the subsequent capture of the phonocardiogram signal according to the second set of capturing properties.
