1. An apparatus, comprising:
- a digital filter unit including a first filter stage and a second filter stage, the digital filter unit configured to receive a sampled signal, wherein the first filter stage is configured to filter the sampled signal based on a first predetermined filter characteristic to generate a first filter stage output signal, and further, wherein the second filter stage is configured to filter the first filter stage output signal based on a second predetermined filter characteristic to generate an output signal associated with a monitored analyte level, wherein the sampled signal includes an over-sampled signal at a frequency of approximately 4 Hz.

8. A method, comprising:
-
receiving, at one or more processors, a sampled signal associated with a monitored analyte level of a user; performing, using the one or more processors, a first stage filtering based on the received sampled signal to generate a first stage filtered signal; performing, using the one or more processors, a second stage filtering based on the generated first stage filtered signal; and generating, using the one or more processors, a filtered sampled signal; wherein the sampled signal includes an over-sampled signal at a frequency of approximately 4 Hz. - View Dependent Claims (9, 10, 11)
