WebMay 27, 2011 · Two examples are presented: a discrete Dirac delta function and an electrocardiogram signal. The results show that, compared with EEMD, the new method here presented also provides a better spectral separation of the modes and a lesser number of sifting iterations is needed, reducing the computational cost. WebIntro to the sift¶ This tutorial is a general introduction to the sift algorithm. We introduce the sift in steps and some of the options that can be tuned. Lets make a simulated signal to get started. This is a fairly complicated signal with a non-linear 12Hz oscillation, a very slow fluctuation and some high frequency noise.
