Patent ID: 8787852

Claim:
A device comprising: a direct path block with an input and an output; and a feedback block with an input and an output; wherein the input of the direct path block is configured to receive a multi-channel input signal having a given frequency range; wherein the output of the direct path block is configured to output an output signal having a baseband frequency range; wherein the output of the direct path block is coupled to the input of the feedback block and the input of the direct path block is coupled to the output of the feedback block; wherein the direct path block comprises a first transposing unit configured to transpose the input signal to the baseband frequency range; wherein the feedback block comprises: a filtering unit configured to filter the transposed signal at the output of the direct path block; and a second transposing unit configured 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; wherein the filtering unit is a low-pass filter and the transposed signal is positively fed back at the input of the direct path block; and wherein the first transposing unit and the second transposing unit are reconfigurable as a function of the given frequency range of the input signal.
