Wavelet Transform: Signal reconstruction from D3 to D6

Hi,

I used the mother wavelet Daubechie 6 to decompose the signals into seven details (D1 to D7). Now, I need to recompose the signals from D3 to D6, which contain the frequency components consistent of my signal.

How can do this?

P.S. I use 'wavedec' function to decompose the signal.

Hi Enrico,

Did you check out wrcoef function, it can be used to reconstruct the wavelet transformed signal. you may need to do some initial preprocessing depends upon your requirement, but it can certainly reconstruct wavelet signals.

I hope this helps you.

Cheers
