A rising edge of the Boolean input u gives a delayed output. A falling edge of the input is immediately given to the output.
Simulation results of a typical example with a delay time of 0.1 s is shown in the next figure.
The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.BooleanNetwork1.
Type: Time (s)
Description: Delay time
Demonstrates the usage of blocks from Modelica.Blocks.MathBoolean
