#32 Question: boundary distortion with wavelets

Hallo, I construct some wavelets e.g. Harr, Sinc, Cardinal Spline
(orthogonal and biorthogonal), but only Harr works good. When I
decompose signal to the lowest level with Sinc or Cardinal Spline and
than reconstruct, I have on the signal boundaries distortion
signal. Harr wavelets basis didn't do it.

It is normal?
Can I do something against it?
I think, that it is caused phase shift of this wavelets. It's true?

My program is on "http://home.zcu.cz/~filip/".
You can get off this program and test it.
If you can help me, call me on e-mail: filip@hermes.zcu.cz .

Thanks.

Filip Jurcicek.
