YIG oscillators are very attractive because of their low noise and wide tuning bandwidth, but they are susceptible to microphonics and to electromagnetic fields.
An earlier paper 1 has described the framework of an experimental pulse code modulation (PCM) system for short-haul telephone trunks.
Encoding an analog signal to digital form entails quantization of amplitude. This process introduces a noise into the analog signal that is recovered from the digits.
The labor shift scheduling problem has traditionally been formulated using the set covering approach proposed by Dantzig, G.B. {[}1954. Operations Research 2 (3), 339-341].
A global reference model covering next generation active and passive networks has been developed for techno-economic evaluations, and an extensive techno-economic analysis has been performed for 10
One of the most stringent specification in modern microwave equipment is the control of spurious levels.
Solar energetic particles (SEPs) provide an opportunity to study in detail the processes of particle acceleration and transport that are ubiquitous in astrophysical plasmas. Tylka et al.
A comparative experimental and analytical study of 62.5, 85 and 100micron core graded index multimode fiber has shown that the 62.5micron design is the least sensitive to macrobending.
This paper studies several different shuffle-equivalent interconnection schemes that can be used within the optical link-stages of photonic switching networks.
Research in the area of automatic speech recognition has progressed to the point at which a wide variety of isolated word recognition systems have been implemented and used successfully for many ap
