Abstract
In a method and apparatus for processing a pair of d.c. signals representing information having angular and amplitude components, in particular, information relating to the unbalance of a body to be balanced, coordinate transformation means are provided in order to transform the coordinates of the two d.c. signals in response to a control signal, the control signal being continually adjusted in a direction dependent upon the polarity of the outputs of the coordinate transformation means, until one of the outputs of the coordinate transformation means becomes 0. In this case, the control signal corresponds to the angular information of the two d.c. voltages, and the output on the other output terminal of the coordinate transformation means corresponds to the amplitude information. Means are also provided for stopping the adjustment of the control signal, whereby a source of d.c. signals corresponding to angular information may be applied to the inputs of the coordinate transformation means, in order to enable adjustment of the d.c. signals so that they correspond to the same angle as the signal applied to the control input of the coordinate transformation means. The two d.c. signals may correspond to the angular position of a body to be balanced.
