## Abstract

Frequency errors in spectral estimates of complex sinusoids in white noise by the ″tapered″ Burg technique are discussed. The tapered Burg technique is a direct result of considering a weighted least-squares fit to the parameters of the all-pole model, subject to Levinson's recursion constraint, in place of the usual unweighted least-squares fit. The algorithmic consequence of this approach is the inclusion of an appropriate taper in the calculation of the partial-correlation coefficients in the usual Burg algorithm. Based on the expression for the frequency error in the spectral estimate of a sinusoid, an optimum taper is then compared with those of the rectangular (untapered Burg) and Hamming tapers.
