Burg's maximum entropy technique is applied to the estimation of power spectra of short sinusoids. The estimated spectral maximum was found to shift in relation to the true maximum. The frequency shifts depend upon the initial phase and the length of the sinusoid. The influence of the number of terms in the prediction error filter, the number of the data samples, and the noise intensity are also considered.
