Question

What is the duty cycle of the output of an astable multivibrator?

(a) 50%

(b) 100%

(c) 75%

(d) 55%

I got this question by my school principal while I was bunking the class.

I'd like to ask this question from Different Types of Multivibrators topic in division Multivibrators of Analog Circuits

Answer 1

Correct option is (a) 50%

The explanation is: An astable multivibrator is a square wave generator. Charging and discharging times of the capacitor are equal and thus the output waveform has a duty cycle of 50%.
