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 ...

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 ...

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 ...

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) ...

New Unit Improves Resolution by 2000 Times, Enabling Engineers to View RF Signal Instabilities and Transients that They Never Knew Existed BEAVERTON, Ore.—Tektronix, Inc., a leading worldwide provider ...

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 phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
