Abstract:
A method of estimating a period and a time delay of a signal, said method comprising the steps of:a) selecting a forgetting factor &agr;; b) electrically receiving an Nth transition time t0 of said signal; c) assigning an Nth weighting factor &ggr;0 to said Nth transition time t0; d) electronically computing a maximum likelihood estimate {circumflex over (T)} of said period using said Nth transition time t0, said forgetting factor &agr;, said Nth weighting factor &ggr;0, and a preceding maximum likelihood estimate {circumflex over (T)} of said period; and e) electronically computing a maximum likelihood estimate {circumflex over (t)}&phgr; of said time delay using said Nth transition time t0, said forgetting factor &agr;, and said Nth weighting factor &ggr;0.
