The term "teleconferencing" refers to two ways electronic communication between two or more groups, or three or more individuals who are in separate locations.
Acoustic Filters to Aid Digital Voice1" By J. L. FLANAGAN (Manuscript received September 19, 1978) Digital conversion of speech requires that the signal be bandlimited.
Summary form only given. As communication systems have become more mobile and portable, we now have situations where audio communication in difficult acoustic environments is common.
Detection of optical radiation using heterodyne mixing was pioneered in the classic experiments of Forrester, Gudmundsen, and Johnson.1 They successfully detected the microwave beat between two Zee
The field of large vocabulary, continuous speech recognition has advanced to the point where there are several systems capable of attaining between 90 and 95% word accuracy for speaker independent
We report on the temperature dependence of the mobility of the two-dimensional electron gas in a variable density AlGaN/GaN field effect transistor, with carrier densities ranging from 0.4x1012cm-2
Acoustic Properties of Longitudinal Displacement in Vocal Cord Vibration By K. ISHIZAKA and J. L.
When a collimated light beam traverses a collimated high-frequency acoustic beam, it is possible for the acoustic beam to scatter light into a single, well-defined angle (into a number of well-defi
Automated Condition Monitoring of machines typically involves the detection and diagnosis of developing defects.
A monostatic Doppler sodar together with a 63-m meteorological tower located in Georgia is used to probe the lower atmosphere that effects propagation in terrestrial line-of-sight microwave transmi
