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 ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Michael] has a thing for playing audio over beepers using a single bit. He’s done it with the Apple ][ and the IBM PC. This time he turns to the ZX Spectrum. He didn’t get quite as ...

In the realm of test equipment, there are a number of items that you don’t know you need until you need one. That’s probably the case with the HP11720A pulse modulator. [Tom] acquired two of these ...

A compact, high voltage pulse modulator for small scale laboratory experiments involving food, biofuel and PEF (pulsed electric field processing) is available from Diversified Technologies, Inc. of ...

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 ...
