DSP Blockset

Block Reference

Blocks -- By Category

The DSP Blockset contains the block libraries described in the following table. Access the libraries with the Simulink Library Browser, which you can open by typing simulink.

Note To learn the basic concepts behind building DSP models with Simulink, see Simulink Review. To find out about using blocks together for common DSP tasks, see Working with Signals.

Select a library for a list of links to the online reference pages of its blocks. (For an alphabetical reference to block reference pages, see Blocks -- Alphabetical List.)

DSP Sinks
Various scopes and blocks for exporting signals to the MATLAB workspace

DSP Sources
Blocks that generate discrete-time signals such as sine waves and uniform random signals

Estimation
Linear prediction, parametric estimation, and power spectrum estimation blocks

Filtering
Digital filter design and implementation, adaptive, multirate, time-varying, and frequency-domain filters

Math Functions
Specialized math operations such as dB conversion and cumulative sum, matrix and linear algebra operations, and polynomial functions such as least squares polynomial fit

Platform-Specific I/O
Blocks for working with specific platforms such as sending audio data to standard audio devices on 32-bit Windows operating systems

Quantizers
A quantizer and uniform encoder and decoder

Signal Management
Buffers, blocks for selecting parts of a signal, blocks for modifying signal attributes such as frame status, and switches and counters

Signal Operations
Blocks such as Convolution, Downsample, Integer Delay, Unwrap, Zero Pad, and Window Function

Statistics
Correlation, Maximum, Mean, RMS, etc.

Transforms
Fast Fourier transform, discrete cosine transform, real and complex cepstrum, etc.
