Jan 9, 2022 at 20:52 | comment | added | Shannon Starr | In your special example, I do not think it is important that $f$ is compactly supported since you are just using the fact that $g$ is band limited. If $F$ decays quickly enough you may still apply the Poisson summation formula for cases other than your special case. But without the band limited assumption for $F$ you are not recovering $\widehat{F}$ from the sample of $F$ on $\mathbb{Z}$. | |

Jan 8, 2022 at 17:10 | comment | added | Michael Hardy | If $\mu=g\,dt$ and $ F(z) = \int_I g(t-z) \, d\mu(t),$ then why not write $ F(z) = \int_I g(t-z) g(t)\,dt$ and dispense with the notation involving $\mu \text{ ?} \qquad$ | |
