Signal Processing Toolbox

Exporting to SPTool

You may want to use your designed filter in SPTool to do signal processing and analysis:

1. Select Export from the File menu. The Export dialog box appears.
2. Select SPTool from the Export To menu.
3. Select Coefficients from the Export As menu to save the filter coefficients or select Objects to save the filter in a filter object.
4. Assign the variable name in the Discrete Filter (or Quantized Filter) text box. If you have variables with the same names in your workspace and you want to overwrite them, select the Overwrite Variables check box.
5. Click the Export button.

1. SPTool opens and the current FDATool filter appears in the Filter area list as the specified variable name followed by (Imported).

Note    If you are using the Filter Design Toolbox and export a quantized filter, only the values of its quantized coefficients are exported. The reference coefficients are not exported. SPTool does not restrict the coefficient values, so if you edit them in SPTool by moving poles or zeros, the filter will no longer be in quantized form.
