Abstract
A system including a first filter module configured to receive an input signal including (i) a first shift in a DC level of the input signal and (ii) a second shift in the DC level of the input signal. The first shift has (i) a first magnitude and (ii) a first duration. The second shift has (i) a second magnitude and (ii) a second duration. The second magnitude is different than the first magnitude. The second duration is greater than the first duration. The first filter module is configured to pass the first shift. The second filter module is configured to detect one or more of (i) the first shift and (ii) the second shift, and in response to detecting one or more of (i) the first shift and (ii) the second shift, filter one or more of (i) the first shift and (ii) the second shift.
