DSP Blockset

Filter Realization Wizard

The Filter Realization Wizard is another DSP Blockset block that can be used to design and implement digital filters. You can use this tool to filter single-channel floating-point or fixed-point signals. Like the Digital Filter Design block, double-clicking a Filter Realization Wizard block opens FDATool. Unlike the Digital Filter Design block, the Filter Realization Wizard starts FDATool with the Realize Model panel selected. This panel is optimized for use with the DSP Blockset.

For more information, see the Filter Realization Wizard block reference page. For information on choosing between the Digital Filter Design block and the Filter Realization Wizard, see Choosing Between Filter Design Blocks.

This section includes the following topics:

• Designing and Implementing a Fixed-Point Filter -- Create a fixed-point filter with the Filter Realization Wizard

Alternatively, you can use other MathWorks products, such as the Signal Processing Toolbox and Filter Design Toolbox, to design your filters. Once you design a filter using either toolbox, you can use one of the DSP Blockset's filter implementation blocks, such as the Digital Filter block, to realize the filters in your models. For more information, see the Signal Processing Toolbox documentation and Filter Design Toolbox documentation. To learn how to import and export your filter designs, see the Importing and Exporting Quantized Filters section of the Filter Design Toolbox documentation.
