Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...

The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms—graphical shapes showing how electrical signals vary over time—rather than just parts ...

The original version of this story appeared in Quanta Magazine. The best perk of Alberto Maspero’s job, he says, is the view from his window. Situated on a hill above the ancient port city of Trieste, ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...
