Abstract

Methods and devices for determining a measurement time period, receiving a plurality of signals associated with a monitored analyte level during the determined measurement time period from an analyte sensor, modulating the received plurality of signals to generate a data stream over the measurement time period, and accumulating the generated data stream to determine an analyte signal corresponding to the monitored analyte level associated with the measurement time period are provided. Systems and kits are also described.

Claims

1. An analyte signal processing method, comprising:

determining a measurement time period;

receiving a plurality of signals associated with a monitored analyte level during the determined measurement time period from an analyte sensor;

modulating the received plurality of signals to generate a data stream over the measurement time period; and

accumulating the generated data stream to determine an analyte signal corresponding to the monitored analyte level associated with the measurement time period.
