blockUnitDelay
Unit Delay Block
Extends from Interfaces.DiscreteSISO (Single Input Single Output discrete control block).
Information
This block describes a unit delay:
1
y = --- * u
z
that is, the output signal y is the input signal u of the previous sample instant. Before the second sample instant, the output y is identical to parameter yStart.
Parameters
| Type | Name | Default | Description |

| Real | y_start | 0 | Initial value of output signal |
| SI.Time | samplePeriod (from DiscreteBlock) | Sample period of component | |
| SI.Time | startTime (from DiscreteBlock) | 0 | First sample time instant |
Connectors
| Type | Name | Default | Description |
