Abstract
Various examples in accordance with the present disclosure provide example methods, systems, and apparatuses that may reduce direct current (DC) bias in biased signal inputs. For example, an example system includes a signal operator and an adaptive filter. The signal operator receives a biased signal input. The adaptive filter provides an estimated bias parameter to the signal operator. The signal operator generates an unbiased signal output based at least in part on the biased signal input and the estimated bias parameter.
