[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 ...

Wrapping your head around phase detectors, ratio detectors ... but thankfully it’s also pretty easy to understand: the pulse counting detector. As [Allan (W2AEW)] notes in the video below ...

Pulse shaping can also be used to generate ... spectral coverage is available from 355 to 1,550 nm with phase modulation of >2π radians. Diffraction loss is <5%. The SLMs have SVGA resolution ...
