NDelay ​

A delay block that delays its input by n timesteps.

Always initializes the intermediate timesteps with initial_condition. Clock-agnostic.

Usage ​

DiscreteComponents.NDelay(initial_condition=0)

Parameters: ​

NameDescriptionUnitsDefault value
nThe number of samples to delay by–
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.
