DOLLAR_f

Delay operator

Block Screenshot

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.

Parameters

  • 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

Interfacing function

  • SCI/modules/scicos_blocks/macros/Linear/DOLLAR_f.sci

Computational function

  • SCI/modules/scicos_blocks/src/fortran/dollar.f (Type 0)
