UnitDifference ​

A unit difference block that computes y[n] = u[n] - u[n-1].

Clock-agnostic.

Usage ​

DiscreteComponents.UnitDifference()

Parameters: ​

NameDescriptionUnitsDefault value
initialization–DiscreteCom...t(; y0=0.0)

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 ​

Behavior of this component cannot be rendered because it includes path variables.
