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.

Why no triggering is used for astable multivibrator?
No triggering is used on an astable multivibrator because it can cause it to become unstable.
Why astable multivibrator called free running oscillator?
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
I am trying to make a seat belt safety light How do you add in a buzzer to an astable circuit which already has and LED?
Use the astable to switch a power transistor and connect the buzzer as the transistor load.
How does an astable circuit work?
astable network means it has only one stable state.so the circuit need trigger input to change to another stage and it automatically changes to the previous stage when the process completed with the use of the capacitor.
What are the differences between monostable and bistable multivibrators?
The bistable multivibrator, or flip-flop, will stay in one or the other state indefinitely, until it is told to change state. The monostable (or astable) multivibrator, or one-shot flip-flip, will stay in one state indefinitely, but once set to the other (triggered) state, it will remain there for only a certain time. There are two varieties. The non-retriggerable one-shot will generate a pulse of known width when triggered, and will complete its cycle no matter what the input does. The retriggerable one-shot will generate a pulse of variable width, minimum being the base time constant, and the pulse can be extended (retriggered) as desired.
What are multivibrators?
Multivibrators are the regenerative circuits used in timing circuits. The are classified as Bistable Multivibrators, Monostable Multivibrators and Astable Multivibrators.
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 a 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.

What does a 555 astable circuit do?
i do not know what an astable circuit does thats why i aksed

Why do you use npn transistors in an astable multivibrator?
You can create an astable multivibrator with PNP, NPN, FETs, or even with NOR gates, NAND gates, or NOT gates. In fact the escapement movement in a mechanical watch is a species of astable multivibrator.
What is the basic difference among the three types of multivibrators?
ur gross!
How many state in astable multivibrator has?
no stablestate
What is astable?
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.
How DC is converted to square pulse?
The easiest way to convert the DC Voltage to pulse is simple astable multivibrator. This can be achieved either directly by astable multivibrator ic's or using normal transistor and resistor combination circuits or by using 555 as astable multivibrator.
Why astable multivibrator called free running oscillator?
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
