### Description

This block realizes a SISO linear system represented by its rational transfer function (in the symbolic variable z). The rational function must be proper.

### Dialog box

- Numerator (z)
  This parameter sets the numerator of the transfer function.
  This must be a polynomial in z.
  Properties : Type 'pol' of size 1.

- Denominator (z)
  This parameter sets the denominator of the transfer function.
  This must be a polynomial in z.
  Properties : Type 'pol' 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: dsslti
