Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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.
