We propose a denoising and segmentation technique for the second heart
sound (S2). To denoise, Matching Pursuit (MP) was applied using a set of
non-linear chirp signals as atoms. We show that the proposed method can
be used to segment the phonocardiogram of the second heart sound into
its two clinically meaningful components: the aortic (A2) and pulmonary
