“…In the past, several investigations have been carried out in order to identify the effects of the EMD when applied to time series issued from various models, such as white, red, or fractional Gaussian noise, (Huang et al, 2003;Flandrin et al, 2004aFlandrin et al, , 2005Wu and Huang, 2004;Rilling et al, 2005;Schlotthauer et al, 2009;Colominas et al, 2012). As a result, it has been consistently shown that, irrespective of the assumed noise model, the EMD acts as an efficient wavelet-like dyadic filter, decomposing the stochastic inputs into IMFs having the same spectral shape but that are shifted in the frequency domain.…”
