Wavelet computation with filter bank - differing results
Convolution is defined as
$$
\left[\tilde{H} * a_{j+1}\right](2k) := \sum_{n=0}^{3} \tilde{h}_na_{j+1,2k-n}
$$
and uses a periodically extended signal. For $\tilde{G}$ it is defined likewise. … Regarding the other two, I came up with the idea that my convolution might be wrong, and I tested two other "modes" of PyWavelets, namely zero-padding (zpd) and periodic-padding (ppd). …
