In this paper, an application of modulating functions method for estimation of the frequency of noisy sinusoids, is proposed. The unknown frequency is updated by introducing a recursive algorithm which is independent by the choice of the modulating functions type. The proposed recursive estimation formula is able to take into account possible abrupt changes or sweep in the frequency of the sinusoidal signal. The goodness of the proposed method is verified through numerical simulations.
