WebMar 21, 2024 · Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. Thus, a 60% duty cycle means the signal is on 60% of the time but off 40% of the time. How do you get a 50% duty cycle in astable multivibrator? WebDuty cycle = 0.694R 1 C/ (0.694R 1 C + 0.694R 2 C) = R 1 / (R 1 +R 2) With this, we can obtain a duty cycle less than 50% by making R1 smaller. Vibration cycle time ( T ): ton + toff = 0.694R 1 C + 0.694R 2 C = 0.694 (R 1 +R 2 )C Frequency (f): 1/T Having shown the various parameters of the 555 timer IC, it’s time to calculate some of them.
