blockChangingEdge

Output y is true, if the input u has either a rising or a falling edge and otherwise it is false (y=change(u))

Extends from Modelica.Blocks.Interfaces.PartialBooleanSISO_small (Partial block with a BooleanInput and a BooleanOutput signal and a small block icon).

Information

A changing edge, i.e., either rising or falling, of the Boolean input u results in y = true at this time instant. At all other time instants, y = false.

The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.BooleanNetwork1.
