At first we will show the example when input and also output terms are uniform placements. For one-dimension system is evident that transfer characteristic is in the middle linear with almost rectilinear course which is making round on the both ends and crossing into the horizontal section of saturation owing to edge effect. Fuzzy system is possible to consider as linear with nonlinear saturation – what is usual for most of real systems.
Shape of convert characteristics for two-dimensional system in middle part is near to inclined plane, only at boundaries are evident nonlinearities like saturation.
