Patent ID: 7496336

Claim:
A weighting circuit for adjusting a feedback control loop to an input signal of said feedback control loop; said feedback control loop comprising a system under control and a device for generating a control difference signal by subtracting a weighted feedback signal from said input signal; said control difference signal being fed to said system under control; said system under control generating an output signal in response to said control difference signal and said output signal of said system under control being multiplied, by means of a weighting circuit by a sequence of multiplication factors for generating said weighted feedback signal; and a frequency bandwidth of said feedback control loop being reduced step by step by said sequence of multiplication factors; wherein each of said multiplication factors for said weighting of said output signal of said system under control is multiplied by said output signal for a specific time duration; and wherein said sequence of said multiplication factors is such that said time duration/bandwidth product of said time duration for halving said frequency bandwidth and said frequency bandwidth of said feedback control loop that is currently set during the adjustment operation is constant during said adjustment operation.
