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 ...

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

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 ...

A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By ...

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission. New research ...
