1. Introduction
The purpose of this document is to instruct users in the use of the
WPL program. The WPL program is intended to provide signal analysis
using the Wavelet Packet transform. This transform maintains
positional as well as frequency information about a signal.
The following conventions are used in this document:
- All keys to be typed in by the user are surrounded in quotes;
i.e. "Enter". If the "Alt", "Shift", or "Ctrl" keys are to be
pressed with a key, it is indicated like "Alt F".
- Strings to type are surrounded with single quotes: i.e. `heart.byt'.
- Check marks are indicated by _/. In WPL, they are displayed with the
square root character.
- The Go Away button which is displayed on the top left of windows is
indicated by the -^- character. This button is equivalent to pressing
the "Esc" key.
- Entries in pull down windows are indicated with | symbols separating
the individual menu entry selections; i.e., FILE|OPEN|SIGNAL.
- All descriptions of edit, directory, or selection windows are
preceded by the associated menu which appears at the top
of the screen.
- Menu entries can alternatively be selected by typing the highlighted
letters. The only exception to this rule is that the top main menu
entries (FILE...) and menu entries for edit window require that the
"Alt" key also be pressed. For example, FILE from the main menu is
selected by pressing "Alt F"
- Gray menu entries are not VALID and cannot be selected
- a trace is defined as a portion of a signal
It may seem that this manual indicates that keys are the principal
method of operating the WPL program; however, the mouse is the
preferred input device. The key documentation is included mainly
as shortcuts to clicking on items with the mouse.
The rest of this document is organized around the main menu of
the WPL program.
2. FILE
This menu contains items dealing with signal files:
- Opening Signal File
- Saving To Signal Files
- Close a Signal window
- Delete a file
2.1 FILE|OPEN|SIGNAL
Invocation "Alt F","I" from the Main Menu

F12 -- Try to load the file name
ESC -- Go back without opening a signal
Description This functions allows the user to open a signal file.
The file type, the format of the signal data, should be
set first. Setting the file type is described in
section 2.1.3. If the FILE TYPE is not the proprietary
Wavelet Packet data format, the IMPORT function is
invoked which is described in section 2.1.4. Note: the
file extension has nothing to do with the FILE TYPE (the
data format) even though when the FILE TYPE is chosen,
the file extension does change to a default value; e.g.
WPL for Wavelet Packet.
There are two ways of specifying a file name. First,
the filename can be typed in from the keyboard. After
typing the file name, the name must be registered with
the "Enter" key and accepted with the "F12" key. If
the file does not exist, pressing "F12" will only
cause the computer to beep.
Secondly, the filename can be selected from a list of
filenames. Using the list of available file names is
described in section 2.1.1. Setting the path of the
list of file names is described in section 2.1.2.
The DRIVE IS NOT READY warning will appear when trying
to access a file on a floppy that has not been inserted.
See section 2.1.5. for a description of what to do next.

F12 -- Close the window
ESC -- Close the window without changes
Description This function allows the user to set the automatic
split parameters. The parameters allow the signal
to be split up into uniform sections or into sections
determined by the energy of the signal.
When splitting the signal into uniform sections, three
parameters are used: Minimum Length, Maximum Length,
and Leading Offset Length. The Minimum Length and
Maximum Length should both be equal to the size of
the uniform section. The Leading Offset Length is
equal to the start of the uniform sections. For
example, Minimum and Maximum Length = 500 and Offset
= 300 will split a 2000 point trace into five traces
(300,500,500,500,200).
When splitting into sections determined by the energy
of the signal, a temporary copy of the signal is squared
and passed through a lowpass filter. The size of the
lowpass filter is determined by the Feature Size
parameter. This version of the signal is split into
sections of a size determined by the Minimum and Maximum
Length. The start of these sections is determined by the
Leading Offset. This function starts sections where the
the signal rises above the noise threshold.

7. TRANSFORM
This menu contains the Wavelet Packet functions.
Here are some definitions that may be useful when reading the following
sections:
coefficient - the energy of a particular frequency and position for
a signal. Notice that frequency as well as position is
maintained in the WPT where it is not in the FFT
segmentation - the grouping of coefficients
transform trace or level - a set of coefficients grouped into
equal segments. This corresponds to a ``windowed FFT''.
basis trace - a set of coefficients grouped into unequal segments,
which allows for adaptation to the signal information content.
reconstruction trace - the inverse WPT of a transform or basis trace.
tableau - the set of all transform traces, basis traces, and
reconstruction traces. The maximum amount of transform traces
in a tableau is N where 2^N = the trace size.
level label - the comment attached to the left of a tableau trace
7.1. TRANSFORM|WPT
Invocation "Alt T","W" from the main menu
Menu WPT MENU: Mark Upper Trace ALL PARAMETERS
WPT MENU: Mark Lower Trace ALL PARAMETERS
Keys Up Arrow -- Move the cursor up
Down Arrow -- Move the cursor down
Enter -- Mark the set of traces to transform
A -- Perform WPT on all traces in the signal
P -- Edit the WPT Parameters see section 7.1.1.
ESC -- Go back to the Main MENU
Description This function allows the user to transform a set of
signal traces using the Wavelet Packet transform.
The user can adjust the WPT parameters (see section
7.1.1.)
A tableau of traces is created for each input signal
trace. The maximum amount of transform traces
in a tableau is N where 2^N = the trace size. The
level which ``best'' suits the signal is highlighted
and marked with BL in the level label. Also the ``best
basis'' is automatically selected by using the entropy
of the coefficients. The best basis is marked with
a BBAS level label.
The numeric cursor information for a transform or
basis trace looks like:
Cursor: L6 F0 P0 C10 N-1.02E3
where
F0 = Frequency 0
P0 = Position 0
C10 = The coefficient or amplitude is 10
N-1.02E3 = The entropy of this frequency
Warning Be aware that any DC offset in the signal will cause
large values in frequency 0. These large values
can throw off the scaling of the tableau, affect the
sensitivity of the phase plane display, and hamper
the automatic subset selection. DC offsets can be
determined with the Average option of VIEW|ANNOTATIONS|
TRACE (see section 4.3.2) and removed with CALCULATE|
SUBTRACT CONSTANT (see section 6.6.).
Warning Make sure that the following amounts of free memory are
are available (see SYSTEM|ABOUT section 8.1) before using
this function.
256 < TRACE SIZE <= 512 FREE MEMORY 73000
128 < TRACE SIZE <= 256 FREE MEMORY 38000
Strange behavior may result if not enough memory is
available.
Warning This function is extremely CPU intensive. Here are some
timings made with a Gateway 386 25MHz:
C6 Wavelet Trace Size = 256 => 5sec
D20 Wavelet Trace Size = 256 => 7sec
C30 Wavelet Trace Size = 256 => 9sec

Ctrl Page Up -- Scroll one trace up
Ctrl Page Down -- Scroll one trace down
Enter -- Select the set of traces to subtract
ESC -- Go back to the main menu
F12 -- Create the basis and go to main menu
Description This function allows the user to define a basis, a disjoint
cover of the transform traces. A basis trace allows the
user to adjust the coefficients to fit the information in
the phase plane.
Transform traces divide the coefficients into
groups called segments. These segments are marked
with vertical lines by choosing the Segmentation option
in the VIEW|ANNOTATIONS|TRACE function (see section
4.3.2.)
A disjoint cover must be defined in the Frequency
Dominant format, which is automatically selected when
using this function. Segments can be selected from
any transform in the tableau. Once a segment has been
selected, no segment above or below may be selected.
The user must select enough segments so that the
number of selected coefficients equal the number of
coefficients in the trace. The selections need to
``cover'' the entire width of a transform trace.
Selections are displayed as shaded regions under the
transform trace. This shading does not show up well
when the transform traces are scaled with large
DC offsets.
The new basis is added after the last basis in the
tableau. The basis is marked with a BAS level label.
When the WPT transform is performed, the ``best basis''
is automatically selected by using the entropy of
the coefficients. The best basis is marked with
a BBAS level label.

DelETE SUBSET = Delete a group of subsets
Keys N -- Select Subsets Manually
A -- Select Subsets Automatically
Del -- Delete a group of subsets
F12 -- Go back to the main menu
Esc -- Go back to the main menu
Description This function allows the user to highlight portions of
transform or basis known as subsets. Subsets are used
to compress signals by choosing only the desirable
coefficients. The goal of the wavelet packet transform
is reduce the information contained in the signal to
just a few coefficients. This compression technique
can only be used in cases where data can be lost.
The user can manually mark a range in a transform or
basis trace (see section 7.6.1).
The subsets can also be selected according to the energy
of the signal (see section 7.6.2). Any previous subsets
are automatically deleted before the auto subsets are
defined. Subsets can also be manually deleted (see
section 7.6.3.).
Subsets are displayed by having the trace drawn in a
different color.
Subsets can also be displayed, set and deleted in the
Phase Plane Display (see section 7.4.).
There are two trace annotations that support the use
of subsets: subset energy and compression ratio. The
subset energy displays to the total energy of all
coefficients defined in subsets. The subset energy also
displays the percentage of the subset energy to the total
energy in the signal. The compression ratio, the ratio
of points in subsets to size of the trace, can also be
displayed at the bottom of the signal window.
The above annotations can give the user an idea how
closely the subsets capture the information in the
original signal. Use the TRANSFORM|RECONSTRUCTION
function described in section 7.7. to see precisely
how well the subsets define the signal.
