Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from ...

Pulse compression is an important technology in modern radar system, which promotes the developments of modern radar technologies towards higher speed and ranging accuracy. The FMCW signals, with the ...

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 ...

RADAR, LiDAR and vision systems play a critical role in enabling advanced driver-assistance systems (ADAS) and autonomous driving (AD). The automotive ADAS markets are forecast to grow at high rates ...

A miniaturized radar chip, developed by researchers at Science Tokyo, advances Integrated Sensing and Communication for Beyond 5G and 6G systems. Measuring just 0.24 mm2 and consuming only 9.8 mW, the ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

We think of optical lasers and microwaves as functioning in distinctly different regions and with disparate modes within the broad electromagnetic spectrum. However, it doesn’t have to be that way, as ...

Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

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) ...
