Introduction
This section describes how to graphically design and implement
digital filters using the Signal Processing Toolbox FDATool GUI.
Filter design is the process of creating the filter coefficients to
meet specific frequency specifications. Filter implementation involves
choosing and applying a particular filter structure to those coefficients.
Only after both design and implementation have been performed can
your data be filtered.
This section includes a brief discussion of applying the completed
filter design and filter implementation using MATLAB command
line functions, such as filter.
For an interactive FDATool demo, type demos at
the MATLAB command line, and select Toolboxes.
Expand the tree, scroll down, and select Signal Processing
Toolbox. Under Filter Design and Analysis, click Introduction
to Filter Design and Analysis Tool.
