DspEdu
2.1 - IIR Filter Design Module
  
|
|
|
The IIR Filter Design Module of DspEdu Covers the design of Digital IIR Filters by Bilinear Transformation. Low Pass , High Pass , Band Pass and
Notch Filters are covered. Three types of approximation functions - Butterworth
, Chebyshev , Inverse Chebyshev - are included.
DspEdu 2.1 is a Perl/Tk GUI program for
Windows Platform to help Students of Digital Signal Processing at Engineering
Undergraduate level in learning introductory DSP and experimenting with
basic concepts of DSP. Course Instructors will also find the program of
help in enhancing the effectiveness of their lectures by using the plot
displays from this program.There are six modules under this program
at present. More modules will be added in future and these modules
will also undergo revision.

This module deals with the IIR Filter
Design by Bilinear Transformation. Low Pass , High Pass , Band Pass and
Notch Filters are covered. Three types of approximation functions - Butterworth
, Chebyshev , Inverse Chebyshev - are included. The user can create, edit
and save IIR Filter designs and the saved designs can be loaded into the
program subsequently. The Frequency response computation results
and the design output can be saved into text files. The plots can be saved
into Postscript files.
The filter transfer function arrived
at in this module can be saved in a format suitable for loading into the
DTFA module for more detailed analysis of frequency response - for
example, to examine how the different second order sections in a Butterworth
or Chebyshev filter contribute to the overall frequency response.

Download Information |
| DspEdu 2.1 is a Shareware. A feature
limited evaluation version is avilable for download from WinSite.Follow
the link below for the download file.

Evaluation Version of DspEdu 2.1
The setup file installs the program
files , default project directories and the required Perl files and modules
under C:\DspEdu by default.DspEdu uses the Perl which gets loaded under
its installation directory even if the target system has Perl installed
in it. However , it does not affect the existing Perl installation , if
any. Neither does it modify any system settings or system files like autoexec.bat,
system.ini, win.ini etc.
The evaluation version allows 15 sessions for each module and each session is time-limited to 10 minutes. There are no feature-limits in the evaluation version.

| Registering DspEdu 2.1 |
The Main Control Panel of the program
has a 'Register DspEdu' button. Clicking on this brings up a dialog box.
Enter the Serial Number and the corresponding Key in the entry boxes provided
for the purpose and click on the OK button to register the program. Successful
registration creates a license file in the installation directory.
You can
obtain the Serial Number and Registration key from RegSoft.
