Are the filters used for wavelet decomposition the same for each level ?

i'm using the wavelet transform decomposition (daubechies 4) and i want to know are the filters used for the decomposition the same for each level ?

Answer 1

[Good mind]

of course, high pass and low pass. the best way to know that is by wavelet toolbox(user's guide,getting started)

Yes i know that there is a high pass and low pass filter at each level but did they have the same coefficients at each level?
