1. A method for processing a signal to identify a consistent portion of the signal, comprising:

  • obtaining a photoplethysmograph (PPG) signal from a sensor;

    selecting a current portion of the PPG signal for analysis;

    identifying one or more signal peaks in the current portion of the PPG signal;

    processing the one or more signal peaks based on a consistency metric;

    comparing the processed one or more signal peaks to the consistency metric to determine if the current portion of the PPG signal is consistent;

    responsive to determining that the current portion of the PPG signal is consistent, determining one or more parameters based at least in part on the current portion of the PPG signal; and

    responsive to determining that the current portion of the PPG signal is not consistent, selecting a next portion of the PPG signal for analysis.
