1. A method comprising:
- inputting biological material to a biosensor;
sensing a response of the biosensor to the biological material by a sensing circuit for a first duration of time;
converting the response to a digital signal;
filtering the digital signal by a digital filter to generate a filtered signal; and
selecting bits of the filtered signal according to a start time to generate a selected signal, the start time being based on a start time signal comprising a rising edge signal, the selected signal comprising the selected bits corresponding to a second duration of time less than the first duration of time, the first duration of time having a first start time before the start time of the second duration of time, the first duration of time having a first stop time after a second stop time of the second duration of time.
