1. An apparatus, comprising:

  • an analyte sensor having a portion in fluid contact with bodily fluid under a skin surface to monitor an analyte level in the bodily fluid;

    a processor operatively coupled to the analyte sensor; and

    a memory operatively coupled to the processor for storing instructions which, when executed by the processor, causes the processor to;

    receive a first signal having a first signal resolution generated by the analyte sensor and associated with the monitored analyte level;

    receive a second signal having a second signal resolution generated by the analyte sensor and associated with the monitored analyte level;

    compare the received second signal to a predetermined threshold level; and

    process one of the received first or the second signals based on the comparison of the received second signal to the predetermined threshold level.
