| Oct 8, 2016 at 2:16 | comment | added | Vesselin Dimitrov | @ChristianRemling: It is the Fourier transform of the first of these functions, $f_1(t)$. This is the 'triangle function' with the vertices $(\pm 1, 0)$ and $(0,1)$, so it meets the three conditions (and is extremal). As for $\widehat{f_2}$, it of course doesn't count as its Fourier transform isn't non-negative. | |
