Алексей Тарабанов:

Extrapolation cannot be implemented by interpolation.

It is important to understand the meaning here

That is, since only one collective harmonic is relevant at the current time, only the last two extrema can be considered valid and significant. It is of course important to understand the distance between them in points and identify where they are, which is achieved using PF.

That is all there is to it.
 
Renat Akhtyamov:

Just one harmonic is a sine wave. And Fourier has nothing to do with it.

The story is processed, it is no longer interesting...

Where is the result?

 
I'll put it another way: come on...
 
Алексей Тарабанов:

Where is the result?

need to do a reverse PF to put the levels on the chart

It's tomorrow.

It's simpler than that. :)

 
Алексей Тарабанов:

maybe, only the levels will be floating ;)

Fixed

 
Алексей Тарабанов:

Fixed

no

the harmonica has a historical memory

history changes, the level changes, at least the price at which it is

besides the amplitude spectrum, there's a phase spectrum, that's what moves the level
