WebJun 1, 2024 · EMD is a fully data-driven approach that can adaptively decompose signal into several zero-mean signal components. In other words, it sifts out a number of intrinsic mode functions (IMFs) from the signal itself. As a result, the total sum of IMFs can match the original signal perfectly. WebThirdly, we proposed a new EMD stopping criterion, determined an optimal number of sifting iterations, employed a new masking signal to fix the mode mixing problem and investigated into the sifting property according to the extremum distribution.
