Abstract
The invention relates to a device comprising a direct path block with an input and an output, and a feedback block with an input and an output, the input of the direct path block being adapted to receive a multi-channel input signal with a given frequency range and the output of the direct path block being adapted to output an output signal with a base band frequency range, the output of the direct path block being coupled to the input of the feedback block and the input of the direct path block being coupled to the output of the feedback block. The direct path block comprises a first transposing unit (4) adapted to transpose the input signal to the base band frequency range and the feedback block comprises a filtering unit (3) adapted to filter the transposed signal at the output of the direct path block, a second transposing unit (5) adapted to transpose the filtered signal to the given frequency range and to feed back the transposed signal at the input of the direct path block. The first transposing unit and the second transposing unit are reconfigurable in function of the given frequency range of the input signal.
