Title: CIRCUIT ARRANGEMENT AND SIGNAL PROCESSING DEVICE
Abstract:
The invention relates to a circuit arrangement (100) and a signal processing device. The circuit arrangement comprises a resonator circuit (101) in order to generate an output signal from an input signal and also comprises a capacitor and an inductor, an input where the input signal can be inputted and an output where the output signal can be outputted. The circuit arrangement also comprises a control circuit (111) for controlling or regulating the quality of the resonator circuit. The control circuit is embodied in such a manner that it controls or regulates the quality of the resonator circuit according to the amplitude of the input signal and/or the output signal.
