ABSTRACT:
For a weighting circuit for adjusting a feedback control loop to an input signal of the feedback control loop the feedback control loop comprises a system under control and a device for generating a control difference signal by subtracting a weighted feedback signal from the input signal. The control difference signal is fed to the system under control which generates an output signal. The output signal is multiplied, by means of a weighting circuit by a sequence of multiplication factors for generating the weighted feedback signal. A frequency bandwidth of the feedback control loop is reduced step by step by the sequence of multiplication factors.
