Since, we used the analytical signals normalized by Hilbert transform of healthy and faulty bearing of induction motor, then extracting vectors forms from time-frequency representation dependant class signal (TFRDCS).
Kingsbury applied the DWT in separate parallel trees; he used two wavelets that were approximately Hilbert transform pairs (a dual tree CWT uses two real DWTs: the first DWT gives the real part of the transform while the second DWT gives the imaginary part (Selesnick et al.
