Signal Processing Toolbox

SPTool: A Signal Processing GUI Suite

SPTool is a graphical user interface (GUI) for analyzing and manipulating digital signals, filters, and spectra. The first few sections of this chapter give an overview of SPTool and its associated GUIs:

• SPTool: An Interactive Signal Processing Environment
• Opening SPTool
• Signal Browser
• Filter Designer
• Filter Viewer
• Spectrum Viewer

The rest of this chapter uses examples to illustrates how to use the GUI-based interactive tools:

• Filtering and Analysis of Noise
• Exporting Signals, Filters, and Spectra
• Accessing Filter Parameters
• Importing Filters and Spectra into SPTool
• Loading Variables from the Disk
• Selecting Signals, Filters, and Spectra in SPTool
• Editing Signals, Filters, or Spectra in SPTool
• Designing a Filter with the Pole/Zero Editor
• Redesigning a Filter Using the Magnitude Plot
• Setting Preferences
• Making Signal Measurements: Using Markers
