Astronomers might be hunting for alien signals in all the wrong places. A new ...

Time-frequency signal analysis techniques furnish a unified framework for examining non-stationary and multicomponent signals by representing their energy distribution jointly in time and frequency.

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more natural source.

Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, ...

When you’re looking to add some wireless functionality to a project, there are no shortage of options. You really don’t need to know much of the technical details to make use of the more ...

Frequency capping has long relied on a static “set it and forget it” mindset: once every 24 hours, three times every seven days and so on. This passive approach to avoiding consumer ad overexposure ...

Charge amplifiers help maintain signal integrity and measurement accuracy for vibration, force, and dynamic pressure testing ...

As cyber threats continue to grow, so does the reality that digital satellite communications can be degraded and denied either through digital or electromagnetic means. If these capabilities are ...

Sound can be represented with both analog or digital audio signals. Analog audio signals use electrical voltage levels. Different types of transducers convert sound to electrical signals and ...
