I believe that conditions on $x$ (which I did not state) may change the point of view. From my memory, for the uniform convergence of the reconstruction, if $x$ is integrable, then you can use $|f|>B$ (but the cosine is not in that class). However, if you only require $x$ to be of exponential type (which apply to the sine then), then you need null spectrum for $|f|\ge B$, see (2.2) in link.springer.com/chapter/10.1007%2F978-3-0348-5432-0_33 | |
