摘要 |
A filter arrangement comprises a first impedance, a second impedance and a subtractor. The first impedance comprises a first connection connected to an input of the filter arrangement and has a first resonant frequency. The second impedance comprises a first connection likewise connected to the input of the filter arrangement and has a second resonant frequency which is higher than the first resonant frequency. The subtractor comprises a first input connected to a second connection of the first impedance, comprises a second input connected to a second connection of the second impedance, and comprises a first connection of the output connected to a first output of the filter arrangement.
