PURPOSE:To obtain a digital quantity as a determined value by hardware which performs fuzzy inference. CONSTITUTION:This circuit is equipped with a weighting adding circuit 2 which multiplies electric signals, showing fuzzy information distributed on plural lines, by values corresponding to the order of the lines and adds the products, a simple adding circuit 3 which adds electric signals without weighting, a constant current source 5 which is connected to the common point of the simple adding circuit, a D/A converter 4 which is connected to the common point of the weighting adding circuit, and a control circuit 7 which outputs a digital quantity to the D/A converter so as to hold the voltage at a downstream point B of the weighting adding circuit and the voltage at a downstream point C of the simple adding circuit at the same level; and the digital value outputted to the D/A converter is used as the determined value. |
