Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two frequency-modulated lasers. By scanning the relative modulation phase between ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

A direct-modulation structure composed of the cross-coupled oscillator with the fast-switched film bulk acoustic resonator (FBAR) is used to enhance the frequency stability under fast OOK/BFSK ...

--(BUSINESS WIRE)--Keysight Technologies, Inc. (NYSE: KEYS) has expanded its radio frequency (RF) and microwave instrument portfolio with six new analog signal generators, two vector signal ...

Remarkably, their method enabled coupling up to eight and nine times the lattice constant while reducing the required modulation frequency by over five orders of magnitude. This is achieved by ...

These emissions are essentially a byproduct of the malware rapidly switching electric signals (On-Off Keying "OOK") within the RAM, a process that isn't actively monitored by security products and ...

The rumbles elephants produce are harmonically complex, and it's difficult to identify important features by looking over things like frequency plots. So, the researchers used two methods of ...
