1998 and Huang et al., 1999 is a recently developed method used for analyzing the nonlinear and non-stationary signal. The supreme innovations of HHT are the establishment of the concept of intrinsic mode function (IMF) and importing of empirical mode decomposition (EMD) (Addison et al., 2009, Macelloni et al., 2011 and Yang et al., 2007). HHT consists of two parts: EMD and HT. EMD turns a nonlinear and non-stationary signal into a definite linear and stationary representation of IMFs.
