Hi barnix,

Congratulations for your knowledge of digital filters and creation of the FFT indicators,I will toy with them because I believe they can be extremely useful..

One question only, for the moment ,I believe that the digital filters generator gives you the peaks in PERIODS,not in Frequencies..so ,if that were true,period 8 means frequency 0.125(as you already know, frequency=1/period)..could you check,please?

Thank you for your observation.
You are right this zones is Priod zones not frequency zones.
In FFT lib we have olso Period zones:
БПФ комплексной функции (прямое и обратное) - Библиотека алгоритмов

You can verify this question with spectrum indicator.

Hi Barnix,
Thanks for sharing this interesting stuff. By the way, I got a question:
How do you determine each of the frequency gap? For example:
1. frequency zone = 8 (6-10) : gap 2, 6-7-(8)-9-10
5. frequency zone = 26 (25-27) : gap 1, 25-(26)-27

Is there any special consideration? Thanks

Cheers,

You can see on Fequency spectrum analysis chart.
For high period domain the gap is +/-2
And for low period domain the gap is +/-1
