Zaghrout, S. Attalah] The necessary and sufficient conditions for all nontrivial solutions of $$\tfrac{d}{{dt}}\left[ {x\left( t \right) - c\int_0^\infty {H\left( s \right)x\left( {t - s} \right)ds} } \right] + a\int_0^\infty {k\left( s \right)x\left( {t - s} \right)ds + bx\left( t \right) = 0} $$ to have ‘zero crossing' are given. Also, an application to level crossing is given.
