PURPOSE:

ScopeFIR designs Finite Impulse Response (FIR) filters using the
Parks-McClellan algorithm.

INSTALLATION NOTES:

ScopeFIR does not require an installation program.  To install it, simply
follow these steps:

1) Unzip the ScopeFIR distribution file into the directory of your choice 
using your favorite zip program.  (If you don't already have a zip program,
"7-Zip" is available free from http://www.7-zip.org.)

*** IMPORTANT NOTE ***

Microsoft now deems their own "HTML Help" format, which ScopeFIR uses, to
be a potential security risk (thanks, Microsoft...)  Therefore, if you
install ScopeFIR on a mapped or shared drive, you will see "Action Cancelled"
each time you try to access ScopeFIR's help system.

The simple solution is to install ScopeFIR somewhere directly on your local
machine, such as on the C: drive.  But if you really need to install ScopeFIR
on a mapped or network drive, more complicated solutions are described at
http://support.microsoft.com/kb/896358.

2) Create a new shortcut for ScopeFIR in the usual way by clicking the right
mouse button on the desktop, then selecting "new" and "shortcut".  At the
prompt, type the path and name for the ScopeFIR.exe file, or browse for it
using the Browse button.  Hit the "Next" button.

3) If desired, change the shortcut name.  Hit the "Finish" button.

That's all there is to it!
