Abstract
A method and circuit for use in determining unbalance of a rotary body having structurally predetermined compensation planes and restricted angular regions thereof in which the unbalance signals of the respective compensation planes are produced and applied to respective first and second inverting amplifiers if the compensation cannot be carried out in the compensation planes and a substitute plane is required. The outputs of the first and second amplifiers are added in a third amplifier whose output value varies as a function of the distance of the substitution plane from a compensation plane so that the output of the second amplifier, with the output of the first amplifier applied to its input, indicates the compensation in the substitution plane and the output of the third amplifier indicates the compensation in the other compensation plane.
