In this video, the multivibrator and types of multivibrators (Astable, Monostable and Bistable Multivibrator) are explained briefly. By watching this video, you will learn the following things: 0:29 What is Multivibrator? 1:12 Astable Multivibrator 1:40 Monostable Multivibrator 3:07 Bistable Multivibrator What is Multivibrator: The multivibrator is the electronic circuit which is used to implement two-state devices like oscillator, timer, and Flip-Flop. Types of Multivibrator: Depending on the number of stable states, the multivibrators can be divided into 3 types. 1) Astable Multivibrator 2) Monostable Multivibrator 3) Bistable Multivibrator Astable Multivibrator: Astable multivibrator does not remain stable in any of the two states. And the output of the multivibrator continuously changes between the two states. This type of multivibrator is used in the design of a relaxation oscillator. Monostable Multivibrator: In monostable multivibrator, there is one stable state and one astable state. The multivibrator output remains in the stable state but whenever an external trigger signal is applied, the output momentarily goes into the astable state. And after some time it comes back into the stable state. The time required to come back into the stable state depends on the passive components like R and C. This type of multivibrator is used as a timer in many applications. Bistable Multivibrator: This type of multivibrator has two stable states. The output used to be in any one of the two stable states. And whenever an external trigger signal is applied, the output goes from one stable state to another stable state. If no triggering action is applied thereafter, then it remains in the new stable state. The bistable multivibrator is one kind of flip-flop circuit. All the three types of multivibrator can be designed using either op-amp, transistor pairs or 555 timer IC. This video will be helpful to all the students of science and engineering in briefly understanding the different types of multivibrator circuits. #Multivibrator #AstableMultivibrator #MonostableMultivibrator #BistableMultivibrator Follow me on YouTube: null Follow me on Facebook: https://www.facebook.com/ALLABOUTELECRONICS/ Follow me on Instagram: https://www.instagram.com/all_about.electronics/ Music Credit: http://www.bensound.com/
