Abstract
In a signal processing arrangement a first and a second input signal associated with the rotating object are received at signal inputs. Amplitude processing blocks are connected to the signal inputs and each have an adjustable gain. A trigonometric processing block has inputs coupled to outputs of the second amplitude processing blocks via respective signal paths. The trigonometric processing block is configured to determine a magnitude value and a phase value based on signals at its inputs. The signal processing arrangement further has compensation blocks configured to store values at the inputs of the trigonometric processing block as respective peak values, when the phase value assumes a respective phase value. A gain value is determined by applying a respective regulation function to respective amplitude errors being based on the peal values, and the gains of the amplitude processing blocks are adjusted based on the respective gain values.
