#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 "".
You can get off this program and test it.
If you can help me, call me on e-mail: .
