Hi all! I figured out the problem posed.

Model:https://www.alteraforum.com/forum/attachment.php?attachmentid=10516

Input func:https://www.alteraforum.com/forum/attachment.php?attachmentid=10514

Furrier coeff:https://www.alteraforum.com/forum/attachment.php?attachmentid=10515

OutputFunc:https://www.alteraforum.com/forum/attachment.php?attachmentid=10517

Now, I want to know: How can I reduce the number of Fourier coefficients.

I want to make the Fourier transform of the period of 8192 points. But I do not want all of 8192 coefficients , I will have enough and no more than 20.
