Frequency Algorithms
Some Frequency Estimation Algorithms
This site presents some Matlab (tm) code for estimation of the frequency of a single, constant tone in noise. While these methods may be extended to the multiharmonic and multi-tone cases, these programs do not include this extension.
Currently no explanations for the algorithms are available in HTML form. The only on-line reference is or here (PDF). The reference list from this, with some linking of authors, is available here in HTML form.
Professor Barry Quinn has recently completed a book on this topic:
Quinn, B.G, Hannan, E.J. (2000) “The Estimation and Tracking of Frequency”
Barry has made matlab code for the algorithms he describes in the book available here.
