A generalization is given for a characterization of the spectral density function of Weyl and Titchmarsh for a singular Sturm-Liouville problem having absolutely continuous spectrum in [0, ∞). A recurrent formulation is derived that generates a family of approximations based on this scheme. Proofs o
