Various segmentation algorithms have been proposed for better classification of the highly nonstationary heart sounds. This paper proposes an improved segmentation technique based on Shannon Energy calculation of the phonocardiogram using adaptive windows. The major focus of the research has been on a simple yet comprehensive signal representation as well(More)
This paper proposes a novel approach for the classification of phonocardiograms based on statistical properties of the PCG signal energy envelograms using fuzzy inference system. Fuzzification of features is done to remove absolute boundaries and assign a degree of association to every segment of the signal with the corresponding heart sound. Since heart(More)
Design of an optimized RF transcutaneous link through inductive coils is an arduous design process which involves complex mathematical modeling to search for optimized design parameters. This paper presents a generalized model which encompasses all possible voltage driven circuit realizations of an inductive link and presents a comparison on the bases of(More)
