Step 3: Applying a Filter to a Signal

When you apply a filter to a signal, you create a new signal in SPTool representing the filtered signal.

To apply the filter filt1 you just created to the signal noise:

  1. Select SPTool from the Window menu in the Filter Designer.
  2. Select the signal noise[vector] from the Signals list and select the filter (named filt1[design]) from the Filters list.


    Press Apply to apply the filter filt1 to the signal noise. The Apply Filter dialog box is displayed
    .
  3. Keep the default filter structure selected in the Algorithm list.
  4. Name the new signal by typing blnoise in the Output Signal field in this dialog box.
  5. Press OK to close the Apply Filter dialog box.
  1. The filter is applied to the selected signal and the filtered signal blnoise[vector] is listed in the Signals list in SPTool.
