[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 ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of ...

The 8-Channel PCM-to-PWM Modulator is a digitally coded conversion IP that translates 8-ch (4 stereo channels) of 16-24bit pulse-code modulated (PCM) input data into pulse-width modulated (PWM) ...

They do not utilize a sinusoidal carrier. Some of these modulation schemes are known by the acronyms PWM ( pulse width modulation), PPM ( pulse position modulation), and PAM ( pulse amplitude ...
