A novel full-wave rectifier turns an audio power amplifier into a simple modulator, that is then used to modulate an ...

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 ...

The FM (frequency-modulated) mode-locked laser is experiencing a renaissance. It is its nature to deliver a broadband and flat-topped spectrum along with a quasi-continuous-wave emission.” ...

A research team in Korea has experimentally demonstrated, for the first time in the world, a nonlinear wave phenomenon that ...

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage ...
