Will narrowing a station’s bandwidth for AM IBOC adversely affect the audio quality? The AM IBOC system FCC-approved for U.S. operation requires using the broadcast station to reduce analog audio ...

Researchers have redefined the limitations and constraints for ultra-fast pulsed lasers. They have produced the first pulsed passively mode-locked nanosecond laser, with a record-low and ...

Narrowband filtering is an excellent tool for obtaining useful data of weak signals in noisy environments. Working for a small aerospace company, the problem of receiving weak telemetry signals is a ...

Shanghai scientists develop ultranarrow bandwidth mode-locked laser with a widely-tunable pulse duration. Shanghai’s ultranarrow bandwidth mode-locked laser. Click for info. Ultranarrow bandwidth mode ...

The use of frequency modulation for the transmission of television signals through a fused-quartz ultrasonic delay gives a high degree of gain stability and relatively low impairment due to spurious ...

We're used to receiving data wirelessly, over Wi-Fi, Bluetooth or cellular networks – our smartphones simply wouldn't work without it. Wireless power is also starting to make its way into devices, but ...

(Nanowerk News) For a fast detection of hazardous biological and chemical agents in air, photo-detectors analyzing scattered light in the ultraviolet (UV) spectral range are often employed. Every ...

Researchers have developed a system that can simultaneously deliver watts of power and transmit data at rates high enough to stream video over the same wireless connection. By integrating power and ...

OCT 95 By Michael Nevins One of the most attractive features of the World Wide Web is the ability to use color graphics and photographs to create an online "brochure" look. Unfortunately, the same ...
