Product Summary

Signal Processing Toolbox™ software is a collection of tools based on the MATLAB^® environment. The toolbox supports a wide range of signal processing operations, from waveform generation to filter design and implementation, parametric modeling, and spectral analysis. The toolbox provides two categories of tools, command-line functions/objects and graphical user interfaces:

Command-Line Functions and Objects

Command-line functions and objects are available in the following categories:

• Discrete-time filter design, analysis, and implementation

• Analog filter design, analysis, and implementation

• Linear system transformations

• Windowing functions

• Spectral analysis and cepstral analysis

• Transforms

• Statistical signal processing

• Parametric modeling

• Linear prediction

• Multirate signal processing

• Waveform generation

Note   For information on objects, see Object-Oriented Programming.

Graphical User Interfaces

A suite of interactive graphical user interfaces are available for

• Filter design and analysis

• Window design and analysis

• Signal plotting and analysis, spectral analysis, and filtering

Supported Data Types

The Signal Processing Toolbox software supports only double-precision inputs. If you input single-precision floating-point or integer data, you should not expect to receive correct results, and in many cases, an error will occur. The Filter Design Toolbox™ product, in conjunction with the Fixed-Point Toolbox™ product, enables single-precision floating-point and fixed-point support for filtering and filter design.
