[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 ...

For instance, studies have modeled the electromagnetic wave energy leakage from large ... for communication using ELF/VLF waves excited by modulated heating of the ionosphere.

fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the modulated carrier changes, the duty cycle of the ...

of a pulse to convey information in single cells. The finding sheds light on how biological rhythms work together to regulate cellular processes. In AM (amplitude modulation) radio, a wave with ...
