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 ...

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 ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
