Digital pulse width modulation (DPWM) has become central to modern power conversion, enabling precise control of switching devices in DC–DC converters, inverters and motor drives. By moving the ...
In single-walled carbon nanotubes, electron–hole pairs form tightly bound excitons because of limited screening. These excitons display a variety of interactions and processes that could be exploited ...
RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...
