DSP Blockset

DSP Block Reference

Using the DSP Block Reference Chapter

This chapter contains complete information on every block in the DSP Blockset in a structured, accessible format. You should turn to this chapter when you need to find information on a particular block. These reference pages are also accessible online via the Help button in each block's dialog box, and through the Help Desk.

To learn the basic concepts behind building DSP models with Simulink, see Chapter 2, "Simulink and the DSP Blockset." To find out about using blocks together for common DSP tasks, see Chapter 3, "Using the DSP Blockset."

What Each Block Reference Page Contains

The block reference entries appear in alphabetical order and each contains the following information:

The block name, at the top of the page.
The purpose of the block.
The library or libraries where the block can be found.
A description of the block's use.
The block's dialog box and parameters. Tunable parameters are indicated by a icon. See "About Tunable Parameters" below.
A See Also list of related blocks and functions.

About Tunable Parameters

Block dialog box parameters that can be adjusted while a simulation is running are called tunable parameters. On the block reference pages these parameters are indicated by a

icon next to the parameter description in the "Dialog Box" section. Parameter descriptions that do not display this icon are not tunable; changing these parameters while the simulation is running generates an error, and suspends the simulation until the error dialog box is dismissed.

Block Library Hierarchy

The DSP Blockset has the following library structure:

Block Library Contents

The DSP blocks in each of these libraries are listed below. Simulink blocks that appear in DSP Blockset libraries (such as Constant) are not included.
