Gabor Spectrogram Honored With R&D Magazine's 1993 R&D 100 Award

July 9, 1993 -- Austin, TX - National Instruments today announced that its
Gabor Spectrogram joint time-frequency analysis (JTFA) algorithm has been
honored with a R&D magazine 1993 R&D 100 Award. The 100 honorees are
selected by the magazine's editors and more than 75 scientific experts.
The award recognizes the Gabor Spectrogram as one of the year's most
technologically significant new products.

The Gabor Spectrogram is a new algorithm for improving JTFA using
techniques that are computationally faster and more accurate than the
traditional short-time Fourier transform (STFT). Other benefits of the
Gabor Spectrogram include improved resolution and signal-to-noise ratio
(SNR).

JTFA is a useful tool that simultaneously analyzes a signal in both the
time and frequency domains. The JTFA method of analysis is commonly used
in industry and research for applications such as speech processing,
sonar, vibration, transient signal detection, and acoustics. JTFA proves
very useful when traditional waveform and frequency analysis are
inadequate.

Engineers and scientists can purchase the Gabor Spectrogram as an add-on
package to the National Instruments LabVIEW instrumentation software.
Gabor Spectrogram users have already discovered numerous applications for
the new technology, including engine diagnostics tests, heart sounds
monitoring, dynamic monitoring of electrical power systems, and speech
recognition.

R&D magazine has honored inventors and scientists around the world since
1963 by annually selecting the 100 most technologically significant new
products and processes. Corporations, government labs, private research
institutes, and universities throughout the world vie for this "Nobel
Prize" of applied research.

Past winners include numerous well known products that are now a part of
everyday life, including; Polacolor film (1963), the electronic video
recorder (1969), anti-lock brakes (1969), the automated teller machine
(1973), halogen lamps (1974), the fax machine (1975), a lens stabling
system for camcorders (1989), low palmetic soybean oil (1991), the photo
CD system (1991), and the Nicoderm transdermal patch (1992).

R&D 100 Awards recognize significant scientific achievement, and are a
hallmark of the innovative spirit that the genius of research and
development demonstrates.
