phase.shift.hilbert

Phase Shift for Hilbert Wavelet Coefficients

Description

Wavelet coefficients are circularly shifted by the amount of phase shift induced by the discrete Hilbert wavelet transform.

Usage

phase.shift.hilbert(x, wf)
phase.shift.hilbert.packet(x, wf)

Arguments

`x`	Discete Hilbert wavelet transform (DHWT) object.
`wf`	character string; Hilbert wavelet pair used in DHWT

Details

The "center-of-energy" argument of Hess-Nielsen and Wickerhauser (1996) is used to provide a flexible way to circularly shift wavelet coefficients regardless of the wavelet filter used.

Value

DHWT (DHWPT) object with coefficients circularly shifted.
