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 ...

Coherent interleaved sampling is a new technique that can acquire data faster with more data points than sequential sampling. Engineers who need to characterize semiconductor devices, high-speed ...

Researchers in the US have recently demonstrated a new way to detect hidden underground ...

For decades, engineers have searched for underground tunnels by sending signals from the surface downward—an approach that can miss what lies below. By reversing that approach, researchers at the ...

A research team led by Prof. Chen Yan at the University of Science and Technology of China (USTC) has taken a leap forward in cardiovascular health monitoring. They have developed a non-invasive radio ...

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 ...

Using the same technology that allows high-frequency signals to travel on regular phone lines, researchers tested sending extremely high-frequency, 200 GHz signals through a pair of copper wires. The ...

Somewhere beyond the influence of the solar wind, more than 25.5 billion kilometers from the nearest human being, Voyager 1 ...
