Step

Generates a step function.

step

Description

Unit Step ensures that the signal changes between two specified levels at a specified time. If the simulation time is less than the value of the parameters Step time, the block output is equal to the value of parameter Initial value. If the simulation time is greater than or equal to the value of the parameter Step time, the output is equal to the value of the parameters. Final value.

Ports

Output

# OUT_1 — output signal
