To detect amplitude deviations and/or offset deviations in two sinusoidal signals (S1, S2), electrically staggered from each other by 90 DEG , both signals (S1, S2) are evaluated by way of threshold stages (K11, K12, K21, K22). The zero passages of the one signal (S1, S2) each indicate trigger time points (1up, 1down, 2up, 2down) for the amplitude of the other signal (S2, S1) in each instance. The output signals (X1, X2, A, &upbar& A, B, &upbar& B) of the threshold stages (K11, K12, K21, K22) are analyzed in the a regulating mechanism. Regulation can take place in accordance with the errors detected.
