Claim One:
1. A fuzzy logic recognition device for recognition of an unknown recognition mode as one of a plurality of target modes, wherein a plurality of predetermined feature classes are selected for the unknown recognition and target modes, and a plurality of predetermined features are selected for each feature class for the target modes, each predetermined feature having a membership with respect to each target mode, said fuzzy logic recognition device comprising: a plurality of sets of feature extraction window means each for storing the predetermined features for one feature class therein, for comparing the stored features with the corresponding features of the unknown recognition mode, for outputting a positive binary signal via one corresponding feature extraction window means where an identicalness condition occurs, and for outputting negative binary signals via the other feature extraction window means where no identicalness condition occurs; a plurality of sets of membership function generators for receiving respective outputs of said feature extraction window means, each membership function generator that receives said positive binary signal generating the memberships of the corresponding predetermined feature with respect to the target modes, and the membership function generators that receive said negative binary signals not generating the memberships; a minimum gate means, coupled to said membership function generator sets, for comparing the memberships with respect to the same target mode, respectively, and for outputting the smallest membership for every one of the target modes; and a maximum gate means, coupled to said minimum gate means, for comparing said memberships outputted from said minimum gate means, and for outputting the largest membership to indicate the unknown recognition mode as one of the target modes.
