The mean properties of the modified maximum entropy method MEM spectral estimator incorporating variable delay are developed for the case of a bandlimited BL complex signal in lowpass noise. Asymptotic cases of long filter length and degeneration to the white noise case are examined in detail. The modified MEM is shown to reproduce the input spectrum to within a scaling factor for delta 1 and to provide a spectral whitening function as delta grows very large. Additionally, examples of spectral distortion for delta greater than unity are shown and qualitatively explained. Author
