Analyte signal processing device and methods
First Claim
1. A signal processing device used for processing analyte related signals, comprising:
- analyte sensor interface electronics for receiving a plurality of analyte related signals from an analyte sensor over a measurement time period; and
a data processing component operatively coupled to the analyte sensor interface electronics for processing the received plurality of analyte related signals, the data processing component including;
a signal filtering component to filter the received plurality of analyte related signals; and
a signal conversion component operatively coupled to the signal filtering component to convert the received filtered plurality of analyte related signals to determine an analyte level associated with a monitored analyte level during the measurement time period;
wherein the signal conversion component includes a clock to generate a plurality of clock signals; and
furtherwherein the signal conversion component synchronizes each of the received filtered plurality of analyte related signals to a corresponding one of the generated plurality of clock signals to generate a frequency data stream based on the received filtered plurality of analyte related signals, where the frequency data stream is accumulated over the measurement time period to filter out one or more signal artifacts, the measurement time period establishing a maximum signal resolution as a function of analog to digital conversion time to obtain a higher signal resolution.
