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: dsslti4
