X to wavelet transform, get the low frequency coefficient of cA as shown in figure
With db5 low-pass filter coefficient x convolution, the data is shown in figure
The result of wavelet transform is not equal to x (convolution) by filter sampling again? , why don't L sampling values and cA is the same, is my code has a problem or understand there is a problem?
