Overview

This example shows that the shapes of dual windows, used for the Gabor transform and expansion, must be close to each other; otherwise, the resulting Gabor coefficients cannot describe the time-varying nature of a signal properly. The shapes of dual windows do not affect perfect reconstruction of the original signal. This program is a shipping example VI included with the Advanced Signal Processing Toolkit for NI LabVIEW.

This software is written in LabVIEW, a graphical programming language designed for scientists and engineers. For more information about LabVIEW, visit ni.com/labview. To try LabVIEW online, visit the LabVIEW Online Evaluation.

Advanced Signal Processing Toolkit Example Programs
The National Instruments Spectral Measurements Toolkit provides a set of flexible spectral measurements in LabVIEW and LabWindows/CVI, including power spectrum, peak power and frequency, in-band power, adjacent-channel power, and occupied bandwidth, as well as 3D spectrogram capabilities. In addition, the Spectral Measurements Toolkit contains VIs and functions for performing modulation-domain operations such as passband (IF) to baseband (I-Q) conversion, I-Q to IF conversion, and generation/analysis of analog modulated signals. The combination of these optimized algorithms and the GHz processing of your PC delivers unmatched measurement throughput.

More information on National Instruments signal processing can be found at the Signal Processing Resource Center.
