The phase delay of the simulated signals, introduced by the linear-phase band-pass filter. A demonstration of the phase delay of two sinusoidal signals with correlated noise and θ0 = 50° (see “Original signal”), introduced by a linear-phase band-pass filter. Please see the 1st panel for the two sinusoidal signals with correlated noise, the 2nd panel for the CEEMD result, and the 3rd panel for the result of the band-pass filter
