The DISPRO software is provided as a Zip
file (to get a trial copy of WinZip go to here)
Before installing DISPRO25 it is suggested
that the following directory structure be created on , for example, drive C: (this is consistent with the discussion in
DISPRO.ZIP should be downloaded to C:\FILTER and the contents extracted
therein. There will be a total of 23 files
extracted: 6 .txt, and 17 .exe. The files are
|The main module
|Graphical specification of filter specifications
|Computation of coefficients for IIR filters, and transformations
from LP prototype to HP/BP/BS
|Design of pass/stop band, and arbitrary magnitude characteristic FIR
linear-phase filters using the Parks-McClellan-Remez algorithm
||Design of Kaiser-windowed FIR filters
||Computation and plotting of frequency responses
||Rounding of coefficients to finite wordlengths
|Simulation of the time-domain response of the filter in floating- or
||Spectrum computation and plotting with FFT
||Coefficient output for specific DSP chips
|HELPT .TXT, HELPS .TXT, HELPG .TXT,
HELPF .TXT HELPD .TXT HELPC .TXT
|Various help files
The main module is DISPRO25.EXE. You should
download and read Manual_1.pdf for information on
starting and running DISPRO25.
You can optionally install in C:\FILTER\UTIL the five
(5) utility programs in Utilities.zip. These
are written in Basic. The purpose of each utility program is described in the comments in each of the .bas files.
I apologize for the state of these utility programs, realizing that a Basic
interpreter is not widely available in today's personal computer world; if you
can find a copy of QBASIC, which was last available circa 1993, it will
execute in a Windows XP 'Command Prompt' window. The syntax of these programs is compatible with
Visual Basic, but you would have to create your own interface. As an
aid, .EXE versions of the two stand-alone programs are included in
Utilities.zip (check the ReadMe file therein).
DISPRO Execution Options:
- Open a Command Prompt window in Win XP/2000
(DOS Prompt in Win 98SE) .
Type CD \Filter <CR> and then DISPRO25 <CR>. You can do
this each time you run DISPRO, or you can create a shortcut on the desktop.
- To create a shortcut in Win XP
|In Windows Explorer go to C:\Filter
|Right-click on DISPRO25(.EXE) to get pop-up
|Select "Create Shortcut". A shortcut
file "Shortcut to DISPRO25" will appear
|With the left mouse button drag this file
out of the Windows Explorer window onto the desktop.
|Right-click the shortcut icon and select
"Properties". In the "Program" tab click the "Change Icon"
button, then click "Browse". Navigate back to C:\Filter and
select DSP.ico. Click OK.
|Finally, right-click the icon again and
select "Rename"; edit the name to just DISPRO25.
A similar process can be followed in Win 98SE to create
DISPRO25 should be run in a window that is sized 80
columns by 25 rows. You can toggle between the window view and the "DOS"
full screen view using Alt-Enter. When DISPRO uses a graphic screen
it will automatically appear in the "DOS" full screen mode, and Alt-Enter will
not switch back to a window.
