Classification: CPC A  G | IPC A  G

Claim 25:
26. A continuous analyte monitoring (CAM) system, comprising:
a wearable device, the wearable device comprising:
a biosensor, wherein the biosensor generates a signal during an analyte monitoring period, the analyte monitoring period comprising a first time period and a plurality of subsequent time periods,
wherein the plurality of subsequent time periods begin sequentially after an end of the first time period;

a time-varying filter coupled to the biosensor; and
a processor coupled to the biosensor and the time-varying filter;
wherein the time-varying filter comprises:
a plurality of low-pass filters coupled in series; and
a plurality of switches, wherein each of the plurality of switches is coupled in parallel with one of the plurality of low-pass filters;

wherein the processor, when executing computer-executable instructions, controls the time-varying filter to apply a level of filtering to the signal during the first time period and each subsequent time period of the plurality of subsequent time periods, the processor:
opening at least one of the plurality of switches for the first time period to apply a first level of filtering to the signal from at least one of the plurality of low-pass filters during the first time period; and
opening at least an additional one of the plurality of switches for each subsequent time period of the plurality of subsequent time periods such that an increased number of low-pass filters of the plurality of low-pass filters apply a level of filtering to the signal relative to an immediately prior number of low-pass filters of the plurality of low-pass filters applying a level of filtering to the signal during an immediately prior subsequent time period,
wherein for each level of filtering for each subsequent time period, the level of filtering is increased relative to an immediately prior level of filtering corresponding to an immediately prior time period to thereby provide consistently increased levels of filtering of the signal across the plurality of subsequent time periods.
