Definition: functional unit that generates an output variable the value of which depends on the sign of the value of its input variable according to the formula

$v\left(t\right)=\left\{\begin{array}{c}{V}_{1}\\ 0\\ -{V}_{1}\end{array}\begin{array}{c}\text{\hspace{0.17em}}\text{for}\text{\hspace{0.17em}}u\left(t\right)>0\\ \text{\hspace{0.17em}}\text{for}\text{\hspace{0.17em}}u\left(t\right)=0\\ \text{\hspace{0.17em}}\text{for}\text{\hspace{0.17em}}u\left(t\right)<0\end{array}$

where
 t is the time; u(t) is the input variable; v(t) is the output variable. V1 is a constant value of the output variable.
