Implement time varying Direct Form II realization of transfer function
Additional Math & Discrete / Additional Discrete
The Transfer Fcn Direct Form II Time Varying block implements a Direct Form II realization of the specified transfer function. The block supports only single input-single output (SISO) transfer functions.
The input signal labeled
Den No Lead contains
the denominator coefficients of the transfer function. The full denominator
has a leading coefficient of one, but it is excluded from the input
signal. For example, a denominator of [1 -1.7 0.72] is represented
by a signal with the value [-1.7 0.72]. The input signal labeled
the numerator coefficients. The data types of the numerator and denominator
coefficients can be different, but the length of the numerator vector
and the full denominator vector must be the same. Pad the numerator
vector with zeros, if needed.
The block automatically selects the data types and scalings of the output, the coefficients, and any temporary variables.
The Transfer Fcn Direct Form II Time Varying block accepts signals of the following data types:
For more information, see Data Types Supported by Simulink in the Simulink® documentation.
Set the initial condition.
Specify the rounding mode for fixed-point operations. For more information, see Rounding. 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.
