| Zusammenfassung: | The present disclosure relates generally to systems and methods for direct current (DC) correction in wireless devices. In one example, a method includes setting a cutoff frequency of a filter at a first frequency, where a signal entering the filter is attenuated based on the cutoff frequency. If a qualified change is detected in a DC component of the signal, the cutoff frequency is set at a second frequency that attenuates more of the signal than the first frequency for a defined time period. The cutoff frequency may then be set to the first frequency after the defined time period. |
