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 ...
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 ...
A variety of ultrawideband system designs — from carrierless, impulse UWB (I-UWB) to multicarrier (MC) UWB — have been pursued recently. I-UWB has several advantages, including simple RF circuitry, ...
