Abstract
Abstract A defuzzifier circuit is used to obtain a manipulated variable for controlling an actuator by using fuzzy information appearing over a plurality of lines. The defuzzifier circuit shares the membership function with a plurality of converting mechanisms and enables a weight to be set externally. <IMAGE>

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
A defuzzifier circuit comprising: a weighted summing circuit adapted to sum electric signals representative of fuzzy information distributed over a plurality of lines after multiplying said signals by respective values corresponding to the grades of said lines; a simple summing circuit adapted to sum said electric signals without weighting; a constant-current source connected to said simple summing circuit; and means for equalizing the voltage at the downstream side of summing resistances of said simple summing circuit with the voltage at the downstream side of weighted summing resistances of said weighted summing circuit.
Claim 2
Dependent Claim
94 words
A defuzzifier circuit comprising: a weighted summing circuit adapted to sum electric signals representative of fuzzy information distributed over a plurality of lines after multiplying said signals by respective values corresponding to the grades of said lines; a simple summing circuit adapted to sum said electric signals without weighting; weight signal generating means capable of setting a weight externally; and means for controlling a circuit portion related to said electric signals so that the output of said simple summing circuit takes a value in accordance with the output of said weight signal generating means.
