The present invention involves a method and apparatus for analyzing two measured signals acquired by a detector (20,320) that are modeled as containing primary and secondary portions. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, the present invention involves utilizing a transformation which evaluates a plurality of possible signal coefficients in order to find appropriate coefficients. Alternatively, the present invention involves using statistical functions or Fourier transform and windowing techniques to determine the coefficients relating to two measured signals. Use of this invention is described in particular detail with respect to blood oximetry measurements.

Cette invention inclut une méthode et un appareil pour analyser deux signaux conçus pour contenir une première et une deuxième portion et captés par un détecteur (20 320). Des coefficients établissent un lien entre les deux signaux selon un modèle défini conformément à cette invention. L'une des applications de l'invention consiste à utiliser une transformation qui permet d'évaluer de multiples coefficients de signaux possibles afin de trouver les coefficients appropriés. La présente invention peut aussi utiliser des fonctions statistiques ou des transformées de Fourier ainsi que des techniques de fenêtrage pour déterminer les coefficients associés à deux signaux mesurés. L'utilisation de cette invention dans le domaine des mesures d'oxymétrie sanguine est décrite de façon particulièrement détaillée.
