Researchers demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. The detector ...

Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

DSOs (digital oscilloscopes) offer a great many advantages over their analog equivalents but as they say, “There’s no such thing as a free lunch.” Digital scopes sample, digitize, and store waveforms ...
