Claim 12:
13. One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by at least one processor, perform a method of filtering a signal over an analyte monitoring period, the method comprising:
identifying a first time period occurring during the analyte monitoring period,
wherein the first time period begins proximate to a start of the analyte monitoring period;

applying a first level of filtering to the signal during the first time period;
identifying a second time period occurring during the analyte monitoring period, wherein the second time period begins after an end of the first time period;
applying a second level of filtering to the signal during the second time period,
wherein the second level of filtering is an increased level of filtering relative to the first level of filtering,
wherein applying the second level of filtering comprises:
opening a first switch in a time-varying filter such that a first low-pass filter comprised in the time-varying filter applies the second level of filtering to the signal, the first switch being coupled in parallel with the first low-pass filter;

identifying a third time period occurring during the analyte monitoring period, wherein the third time period begins after an end of the second time period;
applying a third level of filtering to the signal during the third time period,
wherein the third level of filtering is an increased level of filtering relative to the first level of filtering and the second level of filtering;

identifying subsequent time periods occurring sequentially after the third time period and during the analyte monitoring period,
wherein the subsequent time periods begin sequentially after an end of the third time period; and

applying increased levels of filtering to the signal during the subsequent time periods, 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 subsequent time periods.
