Claim One:
1. A fuzzy syllogistic inference system for performing electrically the modus ponens rule of inference involving a minor premise with a range of confidence between zero and one and major premises with a range of confidence between zero and one and calculating the confidence and fidelity measure of the consequent of the inferences comprising: means for supplying a first electrical signal whose amplitude is in the range between 0 and 1, said amplitude representing the measure of confidence in the truth of the minor premise; means for supplying a second electrical signal whose amplitude is in the range between 0 and 1, said amplitude representing the measure of confidence in the truth of the major premise; first circuit means coupled for receiving the first and second electrical signals and for deriving as a fidelity measure of the consequent a third electrical signal whose amplitude is the difference between the amplitude of the second electrical signal and the complement of the amplitude of the first electrical signal, and second circuit means for deriving as the valid consequent of the inference a fourth electrical signal having the amplitude of the second electrical signal when the third electrical signal is positive.
