Abstract
A method for rapidly estimating power spectral density components in the spectrum of an input signal, by digitizing the input signal over a selected time interval at a selected sample rate; and estimating an autocorrelation sequence for the digitized input signal before generating a solution b.sub.s.sup.0 to the autocorrelation sequence in a Yule-Walker equation by use of Levinson recursion. After generating a control parameter (temperature) .alpha., a non-linear MFE equation, ##EQU1## is solved with b.sub.s.sup.0 as an initial solution. Then, power spectral density components ##EQU2## are generated and recorded as estimates of the input signal.
