Current Filter Information Region

The following information is displayed in the Current Filter Information region.

• Structure indicates which of the dfilt structures is being used for the current filter. (The Filter Design Toolbox provides additional filter structures, which you may see listed if you have installed the Filter Design Toolbox.)
• Order reports the order of the current filter.
• Sections reports the number of sections in the current filter.
• Stable indicates whether the filter is asymptotically stable (Yes) or unstable (No). Filters that have poles on or outside the unit circle are considered unstable.
• Source indicates whether the current filter was designed using FDATool (Designed) or imported from another source (Imported).
• Store filter button stores the current filter design and opens the Filter Manager.
• Filter Manager button opens the Filter Manager dialog box.

If you right-click in the Current Filter Information region, you can view the current filter structure by selecting Show Filter Structure. You can also select an option to convert the filter structure. These options are also on the Edit menu. See Converting the Filter Structure for more information.
