WebNov 17, 2014 · At least for PIC microcontrollers 100% duty cycle means the output will remain high always. This is a note in the CCP in PWM mode in a PIC18F2550: If the PWM duty cycle value is longer than the PWM period, the CCPx pin will not be cleared. Those extremely small falls that you see in Proteus is possibly an error in the simulation. WebNov 3, 2024 · The formula to calculate the duty cycle is: D = \frac {PW} {T}\times 100\%, D = T P W × 100%, where: D D — Duty cycle; PW P W — Pulse width; and T T — Period. Notice … WebDuty cycle is the ratio of time a load or circuit is ON compared to the time the load or circuit is OFF. Duty cycle, sometimes called "duty factor," is expressed as a percentage of ON time. A 60% duty cycle is a signal that is ON 60% of the time and OFF the other 40%. flushing g tube with sterile water
