Multivibrators are the regenerative circuits used in timing circuits. The are classified as Bistable Multivibrators, Monostable Multivibrators and Astable Multivibrators.

What is a quasi stable state in multivibrators?
Every multivibrators have two states:quasi stable and stable state. quasi stable state are triggered state, when a trigger pulse is given the vibrator reaches this state. For example, Astable multivibrators have no triggers so,two stable states. Monostable multivibrators have one trigger so,one stable and one quasi stable which is invoked by the trigger.Same for the Bistable in which two sates are invoked by two triggers.
Is output of astable multivibrator using 555 AC or DC?
it's ac; astable multivibrators are unstable in both of their two states, so they switch back and forth, switching the polarity of the circuit.
What is meant by commutation capacitor?
Usually commutating Capacitors are used in bistable multivibrators. To change the states of two transistors in bistable MVs, a trigger is applied. But due to the capacitance at base of transistor it takes sometime (delay) to change the state. To overcome this problem Commutating capacitors are used. So these are also known as Speed up capacitors or Transpose Capacitors as they speed up the operation.
What is the practical use of astable multivibrator?
it can be used any where, where we need the clock pulse train of low frequancy.like a function generator contains.astable multivibrator is used to produce waveformsas Astable means the circuit is not set to one state or the other but rather oscillates between those states. Therefore the application is signal generation

What is the basic difference among the three types of multivibrators?
ur gross!
What are the different applications of multivibrators?
it is basically used in the timer alaram tat is used in the collage.alo it is used in telephone ckt's for ring tone
What is astable multivibrators?
An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
Is output of astable multivibrator using 555 AC or DC?
it's ac; astable multivibrators are unstable in both of their two states, so they switch back and forth, switching the polarity of the circuit.
What is quasi stable state?
In monostable multivibrators Circuits (quasi stable state) is one of two states, stable state and quasi stable state which is invoked by an external trigger and it will stay there for value determined by time constant.
What is meant by commutation?
Usually commutating Capacitors are used in bistable multivibrators. To change the states of two transistors in bistable MVs, a trigger is applied. But due to the capacitance at base of transistor it takes sometime (delay) to change the state. To overcome this problem Commutating capacitors are used.

What is the difference between oscillator and multivibrators?
Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input
