We discuss some properties of the function sin πχ / πχ which is (sometimes) indicated by the symbol sinc χ. This function is associated with problems involving filtering or interpolating functions. Several integrals are presented and a general rule is discussed.

Keywords : Residue theorem; filtering function; interpolating function.
