Description

The Unit Delay block delays its input by the specified sample period. This block is equivalent to the 1/z discrete-time operator. The block accepts one input and generates one output, which can be either both scalar or both vector. If the input is a vector, all elements of the vector are delayed by the same sample period.

Dialog box

• initial condition

  The output of the simulation for the first sampling period, during which the output of the Unit Delay block is otherwise undefined.

  Properties : Type 'vec' of size -1.

• Inherit (no:0, yes:1)

  When "Inherit" is yes, the block inherit its event input.

  Properties : Type 'vec' of size -1.

Default properties

• always active: no

• direct-feedthrough: no

• zero-crossing: no

• mode: no

• regular inputs:

  - port 1 : size [1,1] / type 1

• regular outputs:

  - port 1 : size [1,1] / type 1

• number/sizes of activation inputs: 1

• number/sizes of activation outputs: 0

• continuous-time state: no

• discrete-time state: yes

• object discrete-time state: no

• name of computational function: dollar
