Filter Direct Form II (Fixed-Point Blockset)

Implement a Direct Form II realization of a filter

Library

Filters

Description

The Filter Direct Form II block implements a Direct Form II realization of the filter specified by the Numerator coefficients and the Denominator coefficients excluding lead parameters. 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

Numerator coefficients: Coefficients for the numerator of the filter.
Denominator coefficients excluding lead: Coefficients for the denominator of the filter, excluding the leading coefficient, which must be 1.0.
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.

Characteristics

Input Ports
