Threshold value switch 1 / 0
Outputs at y a logical "1" if x < S.
Threshold value switch 0 / 1
Outputs at y a logical "1" if x > S.
Threshold value 1 / 0 with
hysteresis
Outputs a logical "1" at y if x < S.
If x >= S + H then y returns to 0.
Threshold value 0 / 1 with
hysteresis
Outputs a logical "1" at y if x > S.
If x >= S + H then y returns to 0.
Limiter
x is limited to the upper limit LU and the lower
limit LL and output at y.
The digital signals MLU and MLL have the
value "1", if the upper or lower limit is active.
