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.

For Boehmians, Integral Transform.
The Hilbert transform
H is defined using the multiplier - isgn(k).
It is shown that the Hilbert transform
is a universal operator in the sense that the peak value of all possible approximation processes diverges unboundedly for some signal in [PW.
This paper derives a novel method of approximating the Hilbert transform
by the use of sine convolution.
Application of the Hilbert transform
to the resultant components yields the energy-frequency-time distribution.
Applications in Mechanical Vibration addresses recent advances in theory and applications of the Hilbert transform
to vibration engineering, enabling laboratory dynamic tests to be performed more rapidly and accurately.
The mathematicians investigate the pointwise convergence of weighted averages linked to averages along cubes, divergent ergodic averages along the squares, the one-sided ergodic Hilbert transform
, deterministic walks in Markov environments with constant rigidity, limit theorems for sequential expanding dynamical systems, and random Fourier-Stieltjes transforms.
Likewise, in the case of Hilbert transform
sampling as in Example 3.
He carries out research into theoretical viscoelasticity, non-linear functional Volterra series, computer algorithms in signal processing, frequency Hilbert transform
, special impact testing, wave dispersion in rods and continuous elements and solution of related inverse problems.
