Description

The Filter Direct Form II Time Varying block implements a Direct Form II realization of the specified filter. The block only supports single input-single output filters.

The block automatically selects the data types and scalings of the output, the coefficients, and any temporary variables.

Parameters and Dialog Box

Initial condition: Set the initial condition.
Round toward: Rounding mode for the fixed-point output.
Saturate to max or min when overflows occur: If selected, fixed-point overflows saturate.
