AFDesign is a MATLAB toolbox for generating a comprehensive set of
elliptic digital and analog filter design alternatives.
AFDesign is easy to use, intuitive, and it is based on standard 
built-in MATLAB commands.

INSTALLATION: AFDesign is distributed in compressed form as the file
afdesign.zip. Decompress afdesign.zip with path names. You obtain

AFD\AFDesign

AFDesign directory has to be appended to the MATLAB path. 

RUNNING: Run MATLAB and execute the following main scripts:

(a) afdesign.m  --  Advanced Filter Design
(b) aadesign.m  --  Analog Advanced Filter Design
(c) dadesign.m  --  Digital Advanced Filter Design
(d) demoaafd.m  --  AFDesign analog design demo
(e) demodafd.m  --  AFDesign digital design demo

DESIGN: After invoking AFDesign.m the the main window appears,
and you can choose a digital or analog filter design.
Click a button and start a filter design by choosing among
many design alternatives D1, D2, D3a, D3b, D4a, D4b, D5 and 2D5.
For example, if you want to design a classical elliptic filter,
click the D1 button, wait a second, and the summary of 
design parameters shows up in the MATLAB command window.
Click the buttons labeled "n+" or "n-" to adjust the filter order.

VISUALIZATION: Plot attenuation versus frequency by using the
PLOT, PASS, TRAN, STOP, or ZOOM buttons.
 
OPEN, VIEW, and EDIT buttons are used to read-in a filter specification
from a file, view the current filter specification, and change 
the current filter specification.

DEMO button loads a demo spec and the D1 design parameters summary.
