Patent ID: 7492150

Claim:
A circuit arrangement for obtaining an output signal from a signal containing at least one alternating component, said circuit arrangement comprising a signal source that supplies this signal, a first peak value detection device for determining a maximum value (Vmax) of the signal, a second peak value detection device for determining a minimum value of the signal, a first signal linking device for obtaining a first resulting signal by additive linking of the signal, the maximum value and the minimum value in accordance with the rule V 1 =K 1 *{ Vs −( V max= V min)/2}, in which K 1 is a freely selectable first constant factor, a second signal linking device for obtaining a second resulting signal by additive linking of the maximum value and minimum value (Vmin) in accordance with the rule V 2=( V max− V min)* K 2, in which K 2 is a freely selectable second constant factor, a first squaring device for squaring the first resulting signal, a second squaring device for squaring the second resulting signal and a third signal linking device for obtaining the output signal by additive linking of the squared first resulting signal and the squared second resulting signal in accordance with the rule Va=K 3*{( 1 / 8 )*( K 1/ K 2) 2 *( V 2) 2 −( V 1) 2 }, in which K 3 is a freely selectable third constant factor.
