Signal Processing Toolbox

Editing Signals, Filters, or Spectra in SPTool

You can edit selected items in SPTool by:

1. Selecting the names of the signals, filters, or spectra you want to edit.
2. Selecting the appropriate Edit menu item:
• Duplicate to copy an item in an SPTool list
• Clear to delete an item in an SPTool list
• Name to rename an item in an SPTool list
• Sampling Frequency to modify the sampling frequency associated with either a signal (and its associated spectra) or filter in an SPTool list

1. The pull-down menu next to each menu item shows the names of all selected items.

You can also edit the following signal characteristics by right-clicking in the display region of the Signal Browser, the Filter Visualization Tool, or the Spectrum Viewer:

• The signal name
• The sampling frequency
• The line style properties

Note    If you modify the sampling frequency associated with a signal's spectrum using the right-click menu on the Spectrum Viewer display region, the sampling frequency of the associated signal is automatically updated.
