ZeroOrderHold ​

Zero-order hold block.

Maps the clocked input signal u to the continuous-time output signal y. Between the ticks of the clock of u, y is held constant at the value u took at the most recent tick.

Before the clock of u has ticked, y equals initial_condition.

Usage ​

DiscreteComponents.ZeroOrderHold(initial_condition=0)

Parameters: ​

NameDescriptionUnitsDefault value
initial_conditionThe value of y before the clock of u has ticked–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.
