Signal Processing Toolbox

Selecting Signals, Filters, and Spectra in SPTool

All signals, filters, or spectra listed in SPTool exist as special MATLAB structures. You can bring data representing signals, filters, or spectra into SPTool from the MATLAB workspace. In general, you can select one or several items in a given list box. An item is selected when it is highlighted.

The Signals list shows all vector and array signals in the current SPTool session.

The Filters list shows all designed and imported filters in the current SPTool session.

The Spectra list shows all spectra in the current SPTool session.

You can select a single data object in a list, a range of data objects in a list, or multiple separate data objects in a list. You can also have data objects simultaneously selected in different lists:

• To select a single item, click on it. All other items in that list box become deselected.
• To add or remove a range of items, Shift+click on the items at the top and bottom of the section of the list that you want to add. You can also drag your mouse pointer to select these items.
• To add a single data object to a selection or remove a single data object from a multiple selection, Ctrl+click on the object.
