摘要：
The invention comprises a method and apparatus for processing signals reflecting a physiological characteristic by performing an error minimizing mathematical combination between signals from at least two independent sensors. For example, the intensity of light is detected following tissue absorption at two wavelengths and the signals are corrected. Preferably, corrected intensity signals are derived by orthogonal regression. In one embodiment, the method and apparatus are used to determine arterial oxygen saturation.
