Fixed-Point Filtering
Fixed-Point Filtering Blocks
The following Signal Processing Blockset blocks enable you
to design and/or realize a variety of fixed-point filters:

Filter Implementation Blocks
The FIR Decimation, FIR Interpolation, Two-Channel Analysis
Subband Filter, Two-Channel Synthesis Subband Filter, and Digital
Filter blocks are all implementation blocks. They allow you to implement
filters for which you already know the filter coefficients. The first
four blocks each implement their respective filter type, while the
Digital Filter block can create a variety of filter structures. All
filter structures supported by the Digital Filter block support fixed-point
signals.
For more information on these filter implementation blocks,
see their reference pages in the Block Reference.

Filter Design and Implementation Blocks
The Filter Realization Wizard block invokes part of the Filter
Design and Analysis Tool from Signal Processing Toolbox software.
This block allows you both to design new filters and to implement
filters for which you already know the coefficients. In its implementation
stage, the Filter Realization Wizard creates a filter realization
using Sum, Gain, and Delay blocks. You can use this block to design
and/or implement numerous types of fixed-point and floating-point
single-channel filters. See Filters and the Filter Realization
Wizard reference page in the Block Reference more information
about this block.
The CIC Decimation and CIC Interpolation blocks allow you to
design and implement Cascaded Integrator-Comb filters. See their block
reference pages for more information.
