Minimum about fuzzy logic
Dilute input terms

As next example we will show fuzzy systems which input terms are thinner distributed in the middle than at the boundaries (condensing towards to the suburbs). Output terms staying equally distributed. Convert characteristic in the middle embodies markedly smaller steepness (thickness) than in the parts which are farther from the middle. Near suburbs there is another curvature in consequence edge effect. Likewise as for two-dimensional system is the area of transfer characteristic less steepness in the middle than at boundaries.
