Math.Sign ​

Outputs the sign of the input.

Computes the output y as the sign of the input u:

This component extends from BlockComponents.Interfaces.SISO

Usage ​

BlockComponents.Math.Sign()

Connectors ​

  • u - This connector represents a real signal as an input to a component (RealInput)

  • y - This connector represents a real signal as an output from a component (RealOutput)

Behavior ​

Source ​

dyad
"""
Outputs the sign of the input.

Computes the output `y` as the sign of the input `u`:

```math
y = \operatorname{sign}(u) = \begin{cases}
  1 & \text{if } u > 0 \\
  0 & \text{if } u = 0 \\
 -1 & \text{if } u < 0
\end{cases}
