摘要：
A system including a first filter module and a second filter module. The first filter module is configured to (i) pass a first DC shift in an input signal and (ii) convert a second DC shift in the input signal to a first component and a second component. The first DC shift is shorter in duration than the second DC shift. The second filter module is configured to detect one or more of (i) the first DC shift and (ii) the first component and the second component of the second DC shift. In response to detecting one or more of (i) the first DC shift and (ii) the first component and the second component of the second DC shift, the second filter module is configured to filter one or more of (i) the first DC shift and (ii) the first component and the second component of the second DC shift.
