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

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 started its first live trial of Digital Sound Broadcasting (DSB) in Nairobi, launching a 12-month pilot that it says could ease chronic congestion in the popular FM (frequency modulation) ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

Kenya has launched its first digital sound broadcasting trial in Nairobi, transmitting 14 stations and promising clearer audio and more broadcasting opportunities.

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 ...

Real-image super-resolution (Real-ISR) seeks to recover HR images from LR inputs with mixed, unknown degradations. While diffusion models surpass GANs in perceptual quality, they often ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

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 ...

Abstract: Short time Fourier transform (STFT) is an excellent two-dimensional time-frequency analysis tool that can effectively analyze the time-frequency characteristics of signals. However, it is ...
