Is this typical behavior for the wavelet method?

Question

Mathematics

Colleagues who had to clean the signal from noise or solve a similar problem (image compression, for example), please look at the screen. Blue - noisy signal, yellow - after wavelet transform. Is this downward jump typical behavior for a method? (I did not find an error in the code; moreover, by applying the reverse transformation, the function was restored).

Answer 1

Well, think for yourself. If the parent wavelet is a continuous function, then how can a series of continuous functions give a discontinuity of the second kind. No, of course it's a bug in the code.
And yes, what, an error somewhere when working with arrays shows a shift in graphs after a break
