[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters.

Dolphin Technology provides Pulse Width Modulator (PWM) IP which can easily modify the shape of the waveform during operation, adjusting both the period and high time through an AMBA® APB slave ...

PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.

“By using pulse shaping you can create the type of modulation you need with a single pulse [from a single laser],” Serati says. Pulse shaping can also be used to generate point-source X-rays ...

EE Times Europe spoke with Tony Chan Carusone, chief technology officer of Alphawave Semi (London, U.K.), to discover the underlying applications driving bandwidth demand and to find out if PAM4 and ...
