Xripple is a graphical user interface (GUI) for the wavelet analysis of
one dimensional signals. This GUI has the following facilities.

* Displays the discrete time wavelet transform and the symmetric
wavelet transform along with the reconstructed signal of any given

* Displays scaling function as well as the mother wavelet. In addition
it displays the magnitude response of the Fourier transform of the
scaling function and the mother wavelet. This is helpful in getting to
understand the time-frequency localization property.

* Options to enable design of a "time dependent filter" by clicking
the mouse.

* Options to select the wavelet coefficients for reconstruction
depending on their absolute value.

* Includes features to store the transform coefficients, the scaling
function, the mother wavelet and the selected transform coefficients for
reconstruction and the reconstructed signal.

* For starters some sample filter coefficients have been included with the
database of the package (eg. Daubhechies, Coiflet). Option available
to give the filter coefficients from an external file.

* Online help.

* Xripple has provision to incorporate any other module for time-
frequency analysis of signals. At present the best basis wave packet
program has some minor bugs ;-( we plan to rectify this in the
near future.

This GUI is developed using Qt libraries for GUI (free Linux version
Qt-0.93). You must have the Qt GUI libraries with you to compile
Xripple. You can ftp the Qt from the following site in

The documentation for Qt can be browsed on the web at
where you will also find other Qt-related links.

How to get a copy of the Xripple?

user: anonymous
passwd: your_email_address
cd pub
get Xripple.tar.gz

Ur_Machine> zcat Xripple.tar.gz |tar xvf -

will have all the files necessay at your machine. You can if you are
using linux directly start using the binary Xripple, else you will have
to read the file called INSTALL which comes with the distribution and
get the qt libraries.

If you have any difficulty in downloading the file, please feel
free to get back to us at this email addresses
