Hi all,
I am newbie in wavelets..
Just read the MATLAB wavelet tutorial as I found it the simplest amongst others to understand..
I want to ask that during the DECOMPOSITION phase in the DWT, when a signal is convolved with HPF and LPF to yield details and approximation..
Q: How are the co-efficients chosen for the HPF and LPF so that they can be convolved with a given signal , say s. Assume, say I use daubechies 2 wavelet.
Q. If we go deeper down the decomposition level, say till 3 or 4, whatever.. do the values of the filter co-effiecients remain the same for HPF and LPF throughout different levels, or do they change ? If they change, how are these values determined then ?
Can someone please help me with these concepts..
Help would be appreciated
Regards
