DSP Blockset

Designing, Analyzing, and Implementing Filters

The DSP Blockset Filter Designs library offers the Digital Filter Design block and the Filter Realization Wizard for designing, analyzing, and then implementing digital filters. Both provide the same filter design and analysis tools, but use different methods of filter implementation suited for different needs. You can use either block to filter signals in your simulations.

Alternatively, you can use other MathWorks products to design and analyze your filters, and then implement them in your models using filter implementation blocks.

Topics Covered.   The following topics show you how to design, analyze, and then implement filters:
