UnitDelay

Delay the clocked input signal for one sample period

Information

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

This block describes a unit delay:

// Time domain description
   y(ti) = previous(u(ti))

// Discrete transfer function
           1
   y(z) = --- * u(z)
           z

that is, the output signal y is the input signal u at the previous clock tick. At the first clock tick, the output y is set to parameter y_start.

Parameters (1)

y_start

Value: 0

Type: Real

Description: Value of output signal at first clock tick

Connectors (2)

u

Type: RealInput

Description: Connector of clocked, Real input signal

y

Type: RealOutput

Description: Connector of clocked, Real output signal
