17. A method comprising:
-
sensing a biological material with a biosensor to generate a first output signal, the first output signal representing a first duration of time, wherein the biosensor operates at a first bio sensor condition; converting the first output signal to a second output signal, wherein the conversion is based on a first conversion parameter; quantizing the second output signal into a digital signal; filtering the digital signal with a digital filter; selecting a portion of the filtered digital signal representing a second duration of time that is smaller than the first duration of time; and based on the selected portion of the filtered digital signal, adjusting the first biosensor condition to a second biosensor condition that is different than the first biosensor condition. - View Dependent Claims (18, 19, 20)
