Signal Processing Toolbox

SPTool: An Interactive Signal Processing Environment

SPTool is an interactive GUI for digital signal processing that can be used to

• Analyze signals
• Design filters
• Analyze (view) filters
• Filter signals
• Analyze signal spectra

You can accomplish these tasks using four GUIs that you access from within SPTool:

• The Signal Browser is for analyzing signals. You can also play portions of signals using your computer's audio hardware.
• The Filter Designer is for designing or editing FIR and IIR digital filters. Most of the Signal Processing Toolbox filter design methods available at the command line are also available in the Filter Designer. Additionally, you can design a filter by using the Pole/Zero Editor to graphically place poles and zeros on the z-plane.
• The Filter Viewer is for analyzing filter characteristics. See Filter Viewer.
• The Spectrum Viewer is for spectral analysis. You can use the Signal Processing Toolbox spectral estimation methods to estimate the power spectral density of a signal. See Spectrum Viewer.
