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. WebCircuit Description Circuit Graph This is a 50% Duty Cycle Astable Multivibrator using the 555 timer IC. An approximately 50% duty cycle is achieved by modifying the control voltage to 1/2 the supply voltage. This allows the periods of low and high states to become equal.
