@Stephen According to the calculations it is correct, but when I look at the graph it looks different. Can you check out Edit 2? It is also interesting that there are different results between Matlab versions.

@TimWescott thank you for your answer. Should we use the wave for analysis instead of generating it for this block? I'm curious about your opinion. Honestly, even if I enter the parameters, I can't get the correct results.

@Marcus Müller I agree with you. The value in LSB of the error in the DNL code. I don't understand how noise can affect the signal ratio. Ultimately, I think the strength of the signal or the strength of the noise is unaffected. For INL, I can define it as nonlinearity occurring outside the linear transfer function line. I could not understand how this nonlinearity creates a harmonic. Or maybe it's touching at a different point, I don't know.

Thank you again for your reply. Opened my mind! @Gillespie

Great explanation! Also thanks for adding the code to the explanation. Finally, does cross-correlation just say a ratio for similarity? Or can we plot the signal that looks like both signals here?

You are right in what you wrote, but how can I understand the similarity from the signal in the graph. Could you please interpret the cross-correlated graph by explaining how the similarity was examined in depth? @Gillipse

The answer you gave is very good, but I could not fully visualize the part of why it repeats in the same period. Especially the animation given in the GIF is very superficial. I would appreciate it if you could elaborate the example you gave for 40 Hz and 60 Hz or link it with a link. I would understand more clearly. @Hilmar
