The invention specifies a method for correcting measurement errors in a time-resolving measurement signal (S) which represents a measurement on a test specimen which carries out a periodic movement at a fundamental frequency (f), wherein the measurement signal (S) is transformed into the frequency domain, wherein a number of amplitude characteristic values (Aj) are determined for a number of harmonic frequencies (fj) of the fundamental frequency (f), wherein a number of correlation characteristic values (Asum, Arel, k) are determined from the or each amplitude characteristic value (Aj), wherein the or each correlation characteristic value (Asum, Arel, k) is used to form a number of correction values (KAj), and wherein a correction signal (FA) for the measurement signal (S) is formed from the or each correction value (KAj). The invention also specifies a torque sensor (1) for the magnetoelastic determination of a torque on a shaft (8), which sensor comprises evaluation electronics (12) which are set up to carry out the method. |
