WebJan 2, 2012 · The Hilbert transform is a technique used to obtain the minimum-phase response from a spectral analysis. When performing a conventional FFT, any signal energy occurring after time t = 0 will produce a linear delay component in the phase of the FFT. WebTo address the issue of the intermittent noise in optical fringe pattern, an adaptive method of noise reduction is given based on empirical mode decomposition (EMD) and Hilbert Huang transform (HHT), and then the wrapped phase is obtained by performing the Hilbert transform on the refined pattern. Firstly, the signal of the fringe pattern is decomposed … WebHilbert transform of a signal x (t) is defined as the transform in which phase angle of all components of the signal is shifted by ± 90 o.
