文摘

The empirical mode decomposition (EMD) is applied in this work. EMD performs signal analysis of non-stationary signals that stem non-linear systems. EMD may produce oscillations with disparate scales; such issue is known as mode mixing. “Mode Mixing” may spoil signal decomposition through EMD. An EMD variant is applied to mitigate mode mixing effects improving signal analysis.
