Researchers use microcomb-based photonic chips to generate ultralow-noise microwave and millimeter-wave signals with record ...

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 ...

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 ...

The "Wow!" signal has been etched with a red marker in the memory of advocates for the search for extraterrestrial intelligence (SETI) since its unveiling in 1977. To this day, it remains one of the ...

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 ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...

How do you make four go into one? Very cleverly, it turns out.
