FDATool Changing Order of Filters in Cascaded Filter

The FDATool Filter Manager now has Up and Down buttons that allow you to rearrange the order in which filters are cascaded.

FDATool Exporting Filter Coefficient Files Added

You can now export filter coefficient files in either decimal or hexadecimal format from FDATool.

FDATool Exporting Lattice ARMA filters to C Header Files Added

You can now export Lattice ARMA filters to C header files from FDATool.

FDATool Code Generation Dialogs Buttons Changed

The code generation dialogs in FDATool now include Generate and Close buttons, instead of OK, Cancel, and Apply buttons.

FDATool Undo/Redo Buttons Removed

The Undo and Redo buttons have been removed from FDATool.

FVTool Numeric Format Selection in Coefficient Viewer

You can now select decimal or hexadecimal numeric format in the FVTool Coefficient Viewer.

dfilt ResetBeforeFiltering Property Renamed

The ResetBeforeFiltering property of the dfilt object has been renamed to PersistentMemory. Refer to the dfilt reference page for information.

Compatibility Consideration

You should update any code that uses the ResetBeforeFiltering property to use the PersistentMemory property.

dfilt NumSamplesProcessed Property Display Changed

The NumSamplesProcessed property no longer displays automatically for every dfilt. You can view this property with the following command, where Hd is a created dfilt:

get(Hd,'NumSamplesProcessed')

Compatibility Consideration

You should update any code that assumes the NumSamplesProcessed is displayed to use the code shown above to display that property.
