PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

[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 ...

What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Ever notice that the ESP32-S3 doesn’t have a digital-to-analog converter? [Chris] did and asserts that he doesn’t care because he can just use the PDM system to get the same result. PDM — pulse ...
