Filter Design Toolbox Release Notes    

Upgrading from an Earlier Release

This section describes the upgrade issues involved in moving from the Filter Design Toolbox 2.1 to Version 2.2.

Moved zerophase Function

The filter analysis function zerophase, which was included in Filter Design Toolbox, has been relocated to the Signal Processing Toolbox. The syntax has changed to take a numerator and a denominator as its first two input arguments. Recall that you must have the Signal Processing Toolbox to use the Filter Design Toolbox, so zerophase remains available to all Filter Design Toolbox customers.
