Application of the nonlinear methods in pneumocardiogram signals

摘要

NIS graphs plotted for the scales between the scales from 0 to 512. Haar wavelet function is used. The NIS of the T-periodic signal vanishes at s = 2T with iscale ≈ 0. For the aperiodic signal, in all scales it does not have a value much smaller than its maximum, with iscale = 0.2474
