We study a tight binding model Hamiltonian of the one-dimensional Bravais lat-tice. This Hamiltonian contains one impurity energy site and two hopping constants between this site and its two nearest neighbours. The formation and properties of the localized states of this model is analysed by virtue of the Green function method.
