FIR ( finite impulse response) filter demo program for the Intel Signal Processing Library (ISPL)

(you need nsp.zip to compile this.)

This is a (freely translated) Delphi port of the demo that can be found in <ISPL installation directory>\examples\firdemo after installation of the self-extracting file spldemo.exe.

Version

    26-Feb-1998

Recent changes

• 26-Feb-1998 (FIRDemo.zip): "NoMath" conditional compilation symbol allows to compile the FIR demo without having the Math unit (not included in Delphi 3 Standard) available.

FIR filter demo installation

I suggest to unpack the zip-file into a private directory. If you have Delphi 3 installed, you should install FIRDemo.dpk first, with Delphi 2 you have to install the component units (XCtrls, ZoomDisp, Tilers) by hand.
If you have the Math unit (not included in Delphi 3 Standard), you may remove the "NoMath" conditional define (dialog Project|Options, page "Directories/Conditionals").
To compile the demo, it is not necessary to install the components at all. When opening FIRDemo.dpr, simply quit the error message

    Class TFloatEdit not found. Ignore the error and continue. <etc.>

by clicking on "Cancel" (*not* "Ignore"). However, you won't be able to examine FIRMain.dfm as long as the components aren't installed.
