Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single ...

AS a mother of two sons, Dominique Stone was used to her children developing selective hearing, especially when it came to carrying out household chores. But appearing to ignore instructions can ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...

Kenya has been using analogue radio, which uses either amplitude modulation (AM) or FM. FM is adopted widely because it gives ...

Advancements in spin-wave filters could revolutionize 6G communication, providing flexible RF front ends with superior ...

Abstract: In this paper, we present a novel orthogonal Doppler frequency modulation (ODFM) to meet the challenging requirements of high-mobility communications. Firstly, we revisit the basic concepts ...

This study offers a valuable contribution to understanding how working memory (WM) shapes neural processing in extrastriate cortex. By applying spectral decomposition to LFP recordings from primate ...

This study explores how exogenous attention operates at the finest spatial scale of vision, within the foveola - a topic that has not been previously explored. The question is important for ...

Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...
