UnitDifference UnitDifference Icon

UnitDifference

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

Clock-agnostic.

Usage

DiscreteComponents.UnitDifference(initial_condition=0)

Parameters:

NameDescriptionUnitsDefault value
initial_conditionThe initial condition of the delayed signal–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.
