## Abstract The problem of the perturbation of an operator having a continuous spectrum and an isolated eigenvalue Ξ»~0~ is considered by means of the theory on embedded eigenvalues. The perturbation is divided up into two parts. One part is used for embedding the isolated eigenvalue Ξ»~0~. This embe

We propose a method of perturbation analysis of nearly sinusoidal oscillators with shifting bias, obtained by generalizing a method recently discussed in the literature [1] (Buonomo A, Di Bello C. IEEE ΒΉransactions on Circuits and Systems, 1996; CAS-43:953}963). The problem of periodic oscillations
