Terrestrial networks have evolved from the low-data-rate voice-centric connectivity of 2G, to support for mobile data and ...

Sometimes, when an audio component dies, the root cause is something electrical. Sometimes, the issue ends up being ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...

Abstract: Wide-bandgap (WBG) devices, such as silicon carbide and gallium nitride, offer higher switching frequencies and power density compared to traditional silicon insulated gate bipolar ...

Oscillators ensure frequency stability in communication devices by generating precise reference signals, reducing drift, and enabling syncronization, modulation, and clarity. Oscillators are circuits ...

Abstract: Charge-based sensors are widely used in vibration testing, inertial navigation, rotational speed testing and so on. The output signals of the charge-based sensors are usually weak, so ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
