Abstract (en)

[origin: EP2150074A2] The arrangement e.g. analog filter (1), has multiple filter planes comprising a first order high pass filter (7) and first order low pass filter (8). An input signal is supplied over a signal branching (6), and an output of the high pass filter or the low pass filter of one of the filter plane is guided over the signal branching on the high pass and the low pass filter of the adjacent filter plane. The filters are formed complementary to each other according to each signal branching. The output of the filters is pulled out for formation of output signals.
