Modulation bandwidths continue to grow, promising higher data rates yet imposing test difficulties. Most test technologies are still rooted in past, narrowband architectures, which are increasingly ...

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 ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the ...

In many ways, high-speed optical communications are following the path that wireless technology has blazed. Of course, optical and wireless networks use different technologies to deal with specific ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

A first-in-human study suggests that tirzepatide modulates abnormal activity in the brain’s nucleus accumbens, reducing food ...

The authors reveal that "we have had the opportunity to investigate for the first time how this signal propagation circuit is modulated by attention, that is, to identify what depths interact with ...
