Description

The Unit Delay block delays its input by the specified sample period. This block is equivalent to the z-1 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
