    Patent number: 5627697
    Abstract: A digital servo control with improved control accuracy, in which the arithmetical mean of a sequential series of n data words is used as a basis for the nominal value for a NOMINAL/ACTUAL value comparison to derive a setting signal. Depending on the value of the arithmetical mean, also intermediate values of adjacent quantization stages may thus be included and taken into consideration for control purposes.
