DSP Blockset

Example: Saving, Importing, and Exporting Filters

Double-clicking the Digital Filter Design block or the Filter Realization Wizard opens the Filter Design and Analysis Tool (FDATool) GUI. FDATool allows you to save, import, and export filters you design. You can use these features as follows:

• Saving a filter design session allows you to save the current filter design settings in FDATool so you can open it later to continue your filter design work.
• Importing filters designed elsewhere allows you to redesign or analyze the filter with FDATool.
• Exporting a filter to the MATLAB workspace or a MAT-file allows other DSP Blockset filter blocks and other applications to use the filter.

The following topics show you how to use FDATool's saving, importing, and exporting features, which apply to both the Digital Filter Design block and Filter Realization Wizard:

• Saving an FDATool Filter Design Session
• Importing a Filter to FDATool
• Exporting a Filter from FDATool
• Signal Processing Toolbox documentation on FDATool
