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

$v (t) = {\begin{matrix} V_{1} \\ 0 \\ - V_{1} \end{matrix} \begin{matrix} for u (t) > 0 \\ for u (t) = 0 \\ for u (t) < 0 \end{matrix}$

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.
