[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 ...

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.

This is the first time we've observed a circadian clock using pulse amplitude modulation, a concept typically associated with communication technology, to control biological functions." ...

ADTRAN, Inc. ADTN recently unveiled the industry’s first full C-band tunable 50Gbit/s SFP56 Dense Wavelength Division Multiplexing (DWDM) with Pulse Amplitude Modulation 4 pluggable transceiver.

Spatial control of the phase and amplitude of a laser beam is ... “By using pulse shaping you can create the type of modulation you need with a single pulse [from a single laser],” Serati ...
