Abstract

An apparatus for inference formation and defuzzification has an arithmetic unit, a memory/register unit, and a controller, wherein crisp output signals can be formed from weighting factors and dimensional scaling numbers dependent on control signals with a weighting factor being provided for each linguistic value of the output variables, the dimensional numbers characterizing the membership functions of the linguistic values of the output variables. The apparatus exhibits high processing speed and requires only low storage space, particularly given definitions of the crisp output signal of greater than or equal to eight bits.
