Sifting iterations

Webwhere h (k) (t) is the temporal estimate of the kth IMF and m n (k) (t) is an estimate of the local mean of h (k) (t) after N sifting iterations. From equation ( 2 ), it can be inferred that EMD considers the signals x ( k ) ( t ) as fast oscillations 〈 h ( k ) ( t )〉 superimposed on slow oscillations m n ( k ) ( t ) , and the sifting process aims to iteratively estimate the … WebGets the number of sifting phase I iterations from the last solve.
