Definition of Multivibrator A multivibrator is an electronic device that gives non-sinusoidal output consists of 2 states. There are generally three types of multivibrators are Monostable, Bistable, and Astable. Monostable has one stable state and one unstable state. Bistable multivibrator has two stable states. Astable M.V has two unstable states. All the MCQs on Multivibrator Multiple…
