File Information

This document constitutes a tutorial on design and implementation of
digital filters in MATLAB. The tutorial is based on functionality from the
Filter Design Toolbox.
    The document covers the design of FIR and IIR single-rate and mul-
tirate filters. It also discusses advanced design techniques such as multi-
rate/multistage decimation/interpolation and the use of special multirate
filters such as allpass-based polyphase IIR filters, CIC filters, and Farrow
    The tutorial focuses on practical aspects of filter design and implemen-
tation, and on the advantages and disadvantages of the different design
algorithms. The theory behind the design algorithms is kept to a minimal.

Required Products Filter Design Toolbox
MATLAB release MATLAB 7.6 (R2008a)
Other requirements Most features shown work in earlier releases of the Filter Design Toolbox.
