METHOD AND APPARATUS FOR ADAPTIVELY AVERAGING DATA SIGNALS |
摘要 |
A method of reducing noise effects in a system for measuring a physiological parameter, comprises the steps of: (a) generating a plurality of measurements derived from at least one wavelength of electromagnetic energy transmitted through living tissue; (b) comparing selected measurements with at least one expected measurement characteristic; (c) assigning one of a plurality of variable weights to each selected measurement based on the comparing step thereby generating a plurality of differently weighted measurements; and (d) averaging a plurality of the differently weighted measurements to obtain a filtered measurement for use in estimating the physiological parameter.
