Abstract (en)
[origin: WO2005093950A1] The circuit arrangement comprises a number of filter stages of a filter bank as well as a number of resonator circuits. The circuit arrangement also contains a resonator control circuit for controlling or regulating the quality of the resonator circuits. This resonator control circuit is configured so that it controls or regulates the quality of at least one resonator circuit according to the amplitude of the input signal and/or of the output signal of the resonator circuit.
