Haar02Orthogonal

public Haar02Orthogonal()

Constructor setting up the orthogonal Haar wavelet coeffs and the scales;

Method Detail

forward

public double[] forward(double[] arrTime)

The forward wavelet transform using the Alfred Haar's wavelet. The arrTime array keeping coefficients of time domain should be of length 2 to the power of p -- length = 2^p where p is a positive integer.

Specified by:

forward in interface WaveletInterface

Overrides:

forward in class Wavelet

Parameters:

arrTime - array keeping time domain coefficients

Returns:

coefficients represented by frequency domain

See Also:

Wavelet.forward(double[])

reverse

public double[] reverse(double[] arrHilb)

The reverse wavelet transform using the Alfred Haar's wavelet. The arrHilb array keeping coefficients of Hilbert domain should be of length 2 to the power of p -- length = 2^p where p is a positive integer. But in case of an only orthogonal Haar wavelet the reverse transform has to have a factor of 0.5 to reduce the up sampled "energy" ion Hilbert space.

Specified by:

reverse in interface WaveletInterface

Overrides:

reverse in class Wavelet

Parameters:

arrHilb - array keeping frequency domain coefficients

Returns:

coefficients represented by time domain
