A signal detected by a Chinese telescope and originally reported as possible evidence of extraterrestrial intelligence is almost certainly due to human factors, one of the researchers on the project ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Modern SDRs evolve from configurable platforms into intelligent wideband sensing systems combining high dynamic range, ...

To meet an increased demand for canceling radio frequency (RF) signal interference, L3 has built a system that can do just that and is planning to expand it into a software capability. L3 is already ...

Following the FCC’s decision to streamline digital FM broadcasting rules, HD Radio owner Xperi is opposing a petition from Press Communications LLC that seeks additional regulatory requirements for FM ...

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 ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...

Analog circuit design guidelines. Digital circuit design guidelines. Differences in the guidelines between the two. Several products in the electronics industry require both analog and digital printed ...

Considerations for dividing analog and digital blocks. Decoupling techniques. Breaking down the board layers. How best to deal with grounding. Similar to building a house, it’s essential to create a ...
