A New Definition of the Intrinsic Mode Function

Authors: Zhihua Yang, Lihua Yang


This paper makes a detailed analysis regarding the definition of the intrinsic mode function and proves that Condition 1 of the intrinsic mode function can really be deduced from Condition 2. Finally, an improved definition of the intrinsic mode function is given.

Keywords: empirical mode decomposition (EMD), Hilbert-Huang transform(HHT), Intrinsic Mode Function(IMF)
