WitrynaThe Empirical Mode Decomposition (EMD) is a powerful technique for signal analysis as it can adaptively decompose signals into components varying in spatial frequency. The spatial frequency represents the repetition per unit distance (the norm in that vector space). EMD generates a series of sparse representations according to the input signal. WitrynaEMD is a method of a decomposing non-stationary signal into a collection of mono-component AM–FM signals. These mono-component signals are referred to as intrinsic mode functions (IMFs). The extraction of the IMFs follows an envelope subtraction process and linear combination of all the IMF-extracted results into the original signal. raymond lemarchand
