In this thesis a dynamical model is introduced for Phonocardiogram based on its morphology which is capable of generating synthetic signals with realistic morphology. The model is for normal Phonocardiograms which includes the two dominant heart sounds, namely the first and the second sounds, and is inspired by the Electrocardiogram dynamical model. In the proposed dynamical model each heart sound is modeled with several Gabor kernels. The ultimate goal of such dynamical model is to establish a model-based processing framework for Phonocardiogram. This framework is devised by employing the dynamical model equations within an Extended Kalman Filter structure, and the simultaneously recorded...
