Sometimes when a project is coming together, you need to cobble a tool together to get it completed. Whether it’s something very involved, like building a 3D printer to fabricate custom parts, or ...

Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what can you do about it? We give you all the details.

Yet the S26 series remains at a low 480Hz PWM rate, as confirmed by company representatives. It could be worse; the standard ...

[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 ...

The Samsung Galaxy S26 Ultra is an eye strain nightmare for some users. Looking for ways to fix this? Here's what to do.

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 ...

Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins ...

Google’s Pixel 8 Pro is a solid smartphone with a great display, but for users sensitive to the PWM refresh rate used on many modern displays, it’s been bordering on unusable. Thanks to a new ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
