Registration entitles the user to technical support and notices of updates to the program. A nominal fee of $50 will be charged for duplications costs. Receipt of payment will register the user. The form should be sent to: Wavelet Packet Laboratory Digital Diagnostic Corp. 26 Rossotto Drive Hamden, CT 06514 Phone: (203)-288-9444 FAX: (203)-287-8765 INTERNET: ddc@cs.yale.edu 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 Menu Open Signal MENU: NAMES PATH TYPES F12DONE Appearance -^---------OPEN DIRECTORY C:\WPL\*.WPL---------------- | | | FILE NAME .\.WPL | | FILE TYPE Wavelet Packet | | | ------------------------------------------------------ where: FILE NAME = The DOS name of the signal file FILE TYPE = The format of the data inside the signal file Keys Typing Keys -- Enter in a file name Enter -- Register the typed in file name Alt N -- Load a list of file names Alt P -- Load a list of directories ALT T -- Load a list of valid signal file formats 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. 2.1.1. FILE|OPEN|SIGNAL NAMES Invocation "Alt N" from the FILE|OPEN|SIGNAL menu Menu Open Signal MENU: F12DONE Appearance -^----------OPEN DIRECTORY C:\WPL\*.WPL--------------- |heart.byt sinxcube.byt ..\ | ----------------------------------------------------- Keys Up Arrow -- Move the cursor up Down Arrow -- Move the cursor down Left Arrow -- Move the cursor left Right Arrow -- Move the cursor right Ctrl Up Arrow -- Scroll up one line Ctrl Down Arrow -- Scroll down one line Page Up -- Scroll up one page Page Down -- Scroll down one page Home -- Move cursor to top left End -- Move cursor to bottom right Ctrl Home -- Move cursor to first entry Ctrl End -- Move cursor to last entry Enter -- Load a file under the cursor F12 -- Load a file under the cursor ESC -- Close the names list window Description This function allows the user to chose a signal file from a list of file names. The path of this window is taken either from the typed in file name or from the PATH list described in 2.1.2. 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. Setting the FILE TYPE is described in section 2.1.3. 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. It is possible to type in `*.*' and view all the files in the current path. If the user selects an entry that ends with \, the path will be changed to that directory. This includes the special entry ..\ which changes the path to the previous directory. 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. 2.1.2.

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. 5.4.

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.

Only a portion of this rectangle can be displayed at a time. Initially, only the bottom half of the phase (containing the lower frequencies) is displayed. Example) Level 2 of a 8 point signal FREQUENCY DOMINANT L2 | 01 02 03 04|05 06 07 08|09 10 11 12|13 14 15 16 | ------------- ----------- ----------- ------------ | | | | | FREQ3 | 13 | 14 | 15 | 16 | | | | | | ------------- ----------- ----------- ------------ | | | | | FREQ2 | 09 | 10 | 11 | 12 | | | | | | ------------- ----------- ----------- ------------ | | | | | FREQ1 | 05 | 06 | 07 | 08 | | | | | | ------------- ----------- ----------- ------------ | | | | | FREQ0 | 01 | 02 | 03 | 04 | | | | | | ------------- ----------- ----------- ------------ POS0 POS1 POS2 POS3 Spikes in the signal will show up as vertical lines in the phase plane while sine waves will show up as a horizontal lines. COLOR SCALE) A color scale showing the correspondence of colors to amplitudes is displayed on the left side of the screen. The numeric cursor, Trace Energy, Subset Energy, and Compression Ratio are always displayed on the bottom of the window. The subset underneath the cursor can be toggled on or off. Subsets are displayed with a thick blue line outlining the coefficient rectangle. 7.5. TRANSFORM|SELECT BASIS Invocation "Alt T","B" from the main menu Menu Basis MENU: Select Transform Segment F12DONE Keys Up Arrow -- Move the cursor up Down Arrow -- Move the cursor down Left Arrow -- Move the cursor left Right Arrow -- Move the cursor right Home -- Move cursor to diagonally up and left End -- Move cursor to diagonally down and left Page Up -- Move cursor to diagonally up and right Page Down -- Move cursor to diagonally down and right Gray Page Up -- Scroll one screen up Gray Page Down -- Scroll one screen down 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. 7.6. TRANSFORM|SELECT SUBSET Invocation "Alt T","S" from the main menu Menus Select Subset MENU: MANUAL AUTOMATIC DelETE SUBSET F12DONE where MANUAL = Select subsets manually AUTOMATIC = Automatically select subsets 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. 7.6.1 TRANSFORM|SELECT SUBSET|MANUAL Invocation "N" from the Select Subset menu Menu Manual Subset MENU: Mark Left Edge Manual Subset MENU: Mark Right Edge Keys Up Arrow -- Move the cursor up Down Arrow -- Move the cursor down Left Arrow -- Move the cursor left Right Arrow -- Move the cursor right Home -- Move cursor to diagonally up and left End -- Move cursor to diagonally down and left Page Up -- Move cursor to diagonally up and right Page Down -- Move cursor to diagonally down and right Gray Page Up -- Scroll one screen up Gray Page Down -- Scroll one screen down Ctrl Page Up -- Scroll one trace up Ctrl Page Down -- Scroll one trace down Enter -- Select the subset range ESC -- Go back to the main menu F12 -- Go back to the main menu Description This function allows the user to manually select the left and right edges of a subset.
