Abstract
A truth value generating basic circuit according to the invention is characterized by having one or a plurality of basic function generator circuits (23, 24) which receive an analog applied input and include an operational amplifier (A.sub.1), and an operation circuit (21, 22). The operation circuit (21, 22) performs a prescribed operation upon receiving, as inputs thereto, an output signal representing a basic function of each basic function generator circuit, and signals corresponding to grades 0 and 1. Alternative embodiments of the truth value generating circuit include and A/D converter (39) for converting an analog input into digital access data which are applied to digital memory (31-34). A truth value generating circuit (TG, TG1-TG3) according to the invention is constituted by providing a plurality of the truth value generating basic circuits, with a different membership function being set in each truth value generating basic circuit.
