MEM spectral analysis was originally proposed by Burg (1967, 1968), who presented the formulation resulting from the application of entropy consideration to spectral determinations. Applications to geomagnetism have been very rewarding. The purpose of this paper is to consider the relation between the frequency shifts observed in the power spectra of relatively short truncated sinusoids added white noise to the noise ratio, the initial phase, the length of the sinusoid, the number of terms in the prediction error filter and the sampling time interval. According to the results for short truncated sinusoids added white noise, it follows that MEM spectral analysis is valuable for the short data samples frequently encountered in water waves problems.
