The Import Filter panel allows you to import a filter. You can access this region by clicking the Import Filter button in the sidebar.
The imported filter can be in any of the representations listed in the Filter Structure pull-down menu and described in Filter Structures. You can import a filter as second-order sections by selecting the check box.
Specify the filter coefficients in Numerator and Denominator, either by entering them explicitly or by referring to variables in the MATLAB workspace.
Select the frequency units from the following options in the Units menu, and for any frequency unit other than Normalized, specify the value or MATLAB workspace variable of the sampling frequency in the Fs field.
To import the filter, click the Import Filter button. The display region is automatically updated when the new filter has been imported.
You can edit the imported filter using the Pole/Zero Editor panel (see Editing the Filter Using the Pole/Zero Editor).
