______________ multivibrator is a square wave oscillator?
Correct answer: B. Astable
- A. Monostable
- B. Astable
- C. Bistable
- D. None of the above
Explanation
An astable multivibrator repeatedly switches between its two states without external triggering, producing a continuous square wave. Monostable circuits generate one pulse, while bistable circuits function as flip-flops.
