Electrified telegraphy was the first practical use of electricity for long-distance communication. This was a tremendous improvement over flashing lights and waving signal flags. The well-known Morse ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

Those of you who work in wireless know the basics, such as the higher the data rate, the wider the bandwidth you are going to use. With spectrum being in such short supply, or perhaps just way too ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. There are currently some new, exotic modulation methods under development. Although these methods ...

Linearity and power efficiency in power amplifiers are critical to the signal quality and battery life of 5G designs. Traditional methods for characterization testing of power amplifiers (PA), however ...

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 ...
