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 inz .

  Properties : Type 'pol' of size 1.

• Denominator (z)

  This parameter sets the denominator of the transfer function.

  This must be a polynomial inz .

  Properties : Type 'pol' of size 1.

Default properties
