Description

The Transport Delay block delays the input by a specified amount of time. It can be used to simulate a time delay. At the start of the simulation, the block outputs the Initial input parameter until the simulation time exceeds the Time delay parameter, when the block begins generating the delayed input.
The Time delay parameter must be non-negative.

Dialog box

• Delay
  The amount of simulation time that the input signal is delayed before being propagated to the output. The value must be nonnegative.
  Properties : Type 'vec' of size 1

• initial input
  The output generated by the block between the start of the simulation and the Time delay.
  Properties : Type 'vec' of size 1

• Buffer size
  The initial memory allocation for the number of points to store.
  Properties : Type 'vec' of size 1
