Sources.BooleanStep ​

Generate step signal of type Boolean.

The Boolean output y is a step signal that transitions from startValue to !startValue at time = startTime.

This component extends from BlockComponents.Interfaces.PartialBooleanSource

Usage ​

BlockComponents.Sources.BooleanStep(startTime=0, startValue=false)

Parameters: ​

NameDescriptionUnitsDefault value
startTimeTime instant of step starts0
startValueOutput before startTime–false

Connectors ​

  • y - This connector represents a boolean signal as an output from a component (BooleanOutput)
