Implement Direct Form II realization of transfer function
Additional Math & Discrete / Additional Discrete
The Transfer Fcn Direct Form II block implements a Direct Form II realization of the transfer function that the Numerator coefficients and Denominator coefficients excluding lead parameters specify. The block supports only single input-single output (SISO) transfer functions.
The block automatically selects the data types and scalings of the output, the coefficients, and any temporary variables.
The Transfer Fcn Direct Form II block accepts signals of the following data types:
For more information, see Data Types Supported by Simulink in the Simulink® documentation.
Specify the numerator coefficients.
Specify the denominator coefficients, excluding the leading coefficient, which must be 1.0.
Set the initial condition.
Specify the rounding mode for fixed-point operations. For more information, see Rounding (Fixed-Point Designer). in the Fixed-Point Designer™ documentation.
Select to have overflows saturate to the maximum or minimum value that the data type can represent. Otherwise, overflows wrap.
When you select this check box, saturation applies to every internal operation on the block, not just the output or result. In general, the code generation process can detect when overflow is not possible. In this case, the code generator does not produce saturation code.
