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 switch 1/0 with
hysteresis
Outputs at y a logical "1" if x < S.
If x >= S + H, then y returns to 0.
Threshold value switch 0/1 with
hysteresis
Outputs at y a logical "1" 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.
