| Mar 4, 2014 at 18:35 | comment | added | hotpaw2 | Isn't this similar to asking if there is a closed form solution to the FT of a arbitrary symmetric function, other than the FT? | |
| Mar 4, 2014 at 17:37 | comment | added | TheGrapeBeyond | @AtulIngle Yes, closed form for position of first null would do as well. The only constraint we have is that the window is symmetric. (Like many of the classical windows we see, hamming, hanning, etc). | |
| Mar 4, 2014 at 17:29 | comment | added | Atul Ingle | Do you want a closed form solution for the first null in the spectrum of an arbitrary window function? I think there is insufficient information to determine that. If all we know is that the window symmetric (even function) we can say for sure that the Fourier transform is symmetric. In theory, one could derive formulas for each window, case-by-case. | |
