KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

Frequency estimation is a critical aspect of modern signal processing, underpinning advances in communications, radar, biomedical imaging and many other fields. At its core, this discipline seeks to ...

A new four-channel vector signal generator claims to serve wideband frequency designs in real-time for demanding wireless applications in 5G, 6G research, satellite communications, and radars. It ...

For many scientific experiments, today’s researchers require a precise reference frequency that allows them to calibrate the time measurements made by their equipment. Such experiments include ...

The disc-shaped resonator measures less than 2 centimeters across, yet the innocuous device is eavesdropping on spacetime. It’s a newly built acoustic wave resonator, and in its first 153 days of ...

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 ...
