FILTER CIRCUIT FOR SUPPRESSING SIGNAL DISTORTION

摘要

The invention relates to a filter circuit which is used, at the hardware level, to prevent charge displacements, which are caused by one or more currents in a frequency splitter (200), producing an interference signal which can cause signal distortion at the output of a current/voltage converter (300) belonging to the filter circuit. This signal distortion would otherwise have to be removed by means of complicated signal post-processing. The voltage profile at the input of the frequency splitter (200) or the current at the second output of the frequency splitter (200) is used in this case to model, by means of a compensation circuit arrangement, a compensation signal which substantially compensates for the interference signal caused by the charge displacements. The invention also relates to an associated method.
