摘要:
Methods and devices for reducing noise effects in a system for measuring a physiological parameter, including receiving an input signal, obtaining an assessment of the signal quality of the input signal, selecting coefficients for a digital filter using the assessment of signal quality; and filtering the input signal using the digital filter, without comparing the filter's output signal with the input signal.
