Find roots in a limited interval

Dear all, Being a Mathematica beginner I struggle to find a solution to a fairly simple problem. I have a function (superposition of several weighted sinc functions) which in principle has infinitely many roots. However I am interested only in lets say roots that are to be found within the limited interval between 0 and 5. I tried to define a system of inequalities of the type Solve[f[t] && t>0 && t<5, t] but no success. I played around with the function Reduce but did not have any success and I am also not sure if this is the right way forward. So the question: Is it possible to define an interval in Mathematica in which I am looking for the roots? Thank you for your time. Regards, Viktor
