Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

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 ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

Operating at millimetRE-wave frequencies introduces a set of engineering challenges that extend far beyond traditional radio frequency testing ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
