FWT_PO: Forward Wavelet Transform (periodized, orthogonal).

Description Usage Arguments Value See Also Examples

View source: R/FWT_PO.R

Description

1. qmf filter may be obtained from MakeONFilter. 2. usually, length(qmf) < 2^(L+1). 3. To reconstruct use IWT_PO.

Usage

1
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.
