Patent ID: 6885933

Claim:
An arrangement for correcting a signal (S), the arrangement comprising: a controller for determining an actuating variable (fr) from an input signal (US); means for providing said signal (S) utilizing said actuating variable (fr) so as to permit said actuating variable (fr) to act on said signal (S); corrective signal determination means for determining at least one corrective signal (ora, fra) from at least one of the following: said input signal (US), said actuating variable (fr), a mean value of said input signal (US) and a mean value of said actuating variable (fr); a mathematical function unit including at least one of an addition member and a multiplication member and said mathematical function functioning to combine said corrective signal (ora, fra) with said signal (S); and, signal evaluation means including: first means for determining a characteristic variable of at least one of the following: said input signal (US), said actuating variable (fr), said corrective signal (ora, fra) and at least one of the mean values of at least one of said input signal (US), said actuating variable (fr) and said corrective signal (ora, fra); second means for comparing said characteristic variable to at least one threshold value (SC1, SC2, SC3); and, third means for making an output signal (A) available for ending said determination of said corrective signal (ora, fra) when reaching or passing through at least one of said threshold values (SC1, SC2, SC3).
