Questions
1

Hello, I try to reconstruct my Fourier data using amplitude and frequency.
I got results but I am not satisfied because I hope my reconstructed Inverse Fourier figure will be almost same in my original Fourier figure but its show that my pick is little different the original pick.
Please help me with how to reconstruct my Fourier data.
I attached my Fourier file here.

Hi.

You could send the CSV files, to practice with your data?

Dear Luis Antonio, Thanks for your reply. Of course, Check the CSV data I attached for your reference.
I hope you will find the way and will help me. This is only for figure one. I hope this data is enough for the reconstruction of Fourier data. If you need any other information please let me know.
