Signal Processing Toolbox

SPTool: A Signal Processing GUI Suite

Overview

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
• Overview of the Signal Browser: Signal Analysis
• Overview of the Filter Designer: Filter Design
• Overview of the Filter Viewer: Filter Analysis
• Overview of the Spectrum Viewer: Spectral Analysis
• Getting Help

The rest of this chapter illustrates in detail how to use the GUI-based interactive tools by walking through some examples:

• Using SPTool: Filtering and Analysis of Noise
• Importing a Signal into SPTool
• Designing a Filter
• Applying a Filter to a Signal
• Analyzing Signals: Opening the Signal Browser
• Spectral Analysis in the Spectrum Viewer
• Exporting Signals, Filters, and Spectra
• Designing a Filter with the Pole/Zero Editor
• Redesigning a Filter Using the Magnitude Plot
• Accessing Filter Parameters in a Saved Filter
• Accessing Parameters in a Saved Spectrum
• 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
• Setting Preferences
• Making Signal Measurements: Using Markers
