Intel Signal Processing Library Demos
This page provides a description of the FIR and Dial Tone demos of the
Intel Signal Processing library.
To download and install the library executables and demos, go to the
Download and Install page.
FIR Demo Description
The FIR demo shows how to use Signal Processing
Library functions to show the frequency response characteristics of FIR filters
based on library functions. The Intel Signal Processing Library
Reference Manual describes these functions in detail.
The FIR demo program is an example of using the
Intel Signal Processing Library functions. The program lets you
manipulate filter parameters with slider controls and observe
graphically the frequency response of an FIR filter based on the
Signal Processing Library's FIR filter function.
Dial Tone Demo Description
The Dial Tone demo shows how to use Signal Processing Library functions to
manipulate touch-tones used in telephony. The Intel Signal Processing Library
Reference Manual describes these functions in detail.
The dialtone demo program uses the Intel Signal Processing
Library functions to encode and decode touchtone (DTMF) signals.
The program uses only standard Windows API calls.
Installing and Running the Signal Processing Library Demos
To run the Signal Processing Library demos, you must first
download spldemo.exe from the Download and Install page.
Afterwards, you must execute firdemo.exe and dialtone.exe to run
the FIR and Dial Tone demos respectively.
See the readme.txt files in \examples\firdemo and in \examples\dialtone
for instructions on how to use the FIR and Dial Tone demos respectively.
