FWT_PO: Forward Wavelet Transform (periodized, orthogonal)
In fabnavarro/rwavelet: Wavelet Analysis
FWT_PO R Documentation
Forward Wavelet Transform (periodized, orthogonal)
Description
1. qmf filter may be obtained from MakeONFilter.
2. usually, length(qmf) < 2^(L+1).
3. To reconstruct use IWT_PO.
Usage
FWT_PO(x, L, qmf)
Arguments
x
1-d signal; length(x) = 2^J.
L
Coarsest Level of V_0; L << J.
qmf
quadrature mirror filter (orthonormal).
Value
wc 1-d wavelet transform of x.
See Also
IWT_PO, MakeONFilter.
Examples
x <- MakeSignal('Ramp', 8)
L <- 0
qmf <- MakeONFilter('Haar')
wc <- FWT_PO(x, L, qmf)
