XWPL is an X based tool to examine one-dimensional real-valued signals using
|
||
|
|
wavelets and wavelet packets. It has been designed to be as easy to use as
|
||
|
|
possible for beginners. It is intended more as an educational and exploratory
|
||
|
|
tool than as a numerical analysis program, even though it uses fast, optimized
|
||
|
|
wavelet and wavelet packet transforms.
|
||
|
|
|
||
|
|
In short, wavelets are a way to analyze a signal using base functions which
|
||
|
|
are localized both in time (as diracs, but unlike sine waves), and in
|
||
|
|
frequency (as sine waves, but unlike diracs). They can be used for efficient
|
||
|
|
numerical algorithms and many DSP or compression applications.
|
||
|
|
|
||
|
|
The mathematical theory behind wavelets (and other related transforms) is
|
||
|
|
given in the appendix of the XWPL reference manual.
