Duty cycle in astable multivibrator
WebJun 20, 2024 · The duty cycle, the ratio of the time tc during which the output is high to the total time period T is given as % duty cycle, D = tc / T * 100 = (RA + RB) / (RA + 2RB) * 100 From the above equation it is obvious that square wave (50 % duty cycle) output can not be obtained unless R A is made zero. WebPWM with Astable Multivibrator output waveform Note that the duty cycle of the output signal is approximately around 50% while the low/high voltage values tend to reach the positive/negative supply values. Extra Activity In the previous example we generated a 50% fixed duty cycle PWM using astable multivibrators.
