Claim One:
1. A method for measuring a physiological parameter of a human, comprising the acts of: analyzing, by using a processor, an energy density of a signal having a physiological component and a non-physiological component to determine one or more changes in the energy density of the signal over time; determining, by using the processor, based on the one or more changes in the energy density of the signal over time, a warping function configured to enable identification of characteristics of the signal corresponding to the non-physiological component; stretching or compressing along a time scale, by using the processor, the signal having the physiological component and the non-physiological component by using the warping function to produce a warped signal; stretching or compressing, by using the processor, a signal quality indicator by using the warping function to produce a warped signal quality indicator; identifying, by using the processor, the non-physiological component of the signal based on an analysis of the warped signal with the warped signal quality indicator; and using the physiological component of the signal and disregarding the non-physiological component of the signal to determine the physiological parameter.
