20.6.4.5. Transfer Function

The Transfer Function block implements a transfer function.

The system is defined by

\(H(s)=\frac{NUM(1)s^{NNUM-1}+NUM(2)s^{NNUM-2}+...+NUM(NNUM)}{DEN(1)s^{NDEN-1}+DEN(2)s^{NDEN-2}+...+DEN(NDEN)}\)

where,
\(NUM()\) are the coefficients of the numerator
\(DEN()\) are the coefficients of the denominator
\(NNUM\) and \(NDEN\) are the numbers of numerator and denominator coefficients.

Parameter(s)

Description

Numerator

Enter the coefficients of the numerator in descending powers of s. If Numerator is a matrix with multiple rows, the block outputs the multiple output signals.

Denominator

Enter the coefficients of the denominator in descending powers of s.

Abs tolerance

Enter the value for the Absolute tolerance.

  • If the Abs tolerance is inputted as -1, the value defined in the Simulation Parameter dialog box is used.

  • If the Abs tolerance is inputted as a value, this value is used instead of the value defined in the Simulation Parameter dialog box.
