Thank you, Robert! I'll try it. I'll post here if I have a decent results.

Thanks, Robert. I agree with you. From the second picture we could see that there are more than one amplitudes. I wrongly wrote my title. Do you have any idea how to get this amplitudes, I think I need to use a normalization, so I could plot exactly the same as in the second picture. But maybe there are needed to be evaluated also some other algorithms, before that?

A discrete signal in general does not have a single amplitude and a single phase. You need to get familiar with spectral analysis / Fourier analysis.
