In this paper we propose a procedure to correct Jain’s algorithm, which in certain situations fails in correctly estimating the frequency by indicating frequency values that are very far from the real frequency. It happens because the two points considered for the method proposed by Jain are not on the same lobe. Thus, a method is proposed according to which these points are chosen so that the results are improved.
Keywords: frequency estimation, interpolation, algorithm, Discrete Fourier Transform, modal analysis.
