Astable Multivibrator working principle in tamil

Astable multivibrator Circuit working Principle of Operation.
Astable Multivibrators are free running oscillators which oscillate between two states continually producing two square wave output waveforms.
Regenerative switching circuits such as Astable Multivibrators are the most commonly used type of relaxation oscillator because not only are they simple, reliable and ease of construction they also produce a constant square wave output waveform.
Unlike the Monostable Multivibrator or the Bistable Multivibrator we looked at in the previous tutorials that require an “external” trigger pulse for their operation, the Astable Multivibrator has automatic built in triggering which switches it continuously between its two unstable states both set and reset.
The Astable Multivibrator is another type of cross-coupled transistor switching circuit that has NOstable output states as it changes from one state to the other all the time. The astable circuit consists of two switching transistors, a cross-coupled feedback network, and two time delay capacitors which allows oscillation between the two states with no external triggering to produce the change in state.
In electronic circuits, astable multivibrators are also known as Free-running Multivibrator as they do not require any additional inputs or external assistance to oscillate. Astable oscillators produce a continuous square wave from its output or outputs, (two outputs no inputs) which can then be used to flash lights or produce a sound in a loudspeaker.
The basic transistor circuit for an Astable Multivibrator produces a square wave output from a pair of grounded emitter cross-coupled transistors. Both transistors either NPN or PNP, in the multivibrator are biased for linear operation and are operated as Common Emitter Amplifiers with 100% positive feedback.
This configuration satisfies the condition for oscillation when: ( βA = 1∠ 0o ). This results in one stage conducting “fully-ON” (Saturation) while the other is switched “fully-OFF” (cut-off) giving a very high level of mutual amplification between the two transistors. Conduction is transferred from one stage to the other by the discharging action of a capacitor through a resistor
Thank you for watching

I have searched many many videos to understand this circuit. Finally ended up here. You are fantastic sir. Very Very clear Explanation. None of them talked about component tolerance but you made a clear point. Thanks a lot Sir. :)

[@randomfacts3769]

I feel very difficult to understand multivibrator circuit now I understand clearly thank you sir for your wonderful teaching

[@sabugeorge8675]

really you are super.No words to explain aboutyour teaching ability.Hats off sir

[@ahmdfahm]

I know the multiple vibrators circuit, but I didn't know the cycle of changing status until cleared by your changing circuit. Tnx.

[@sankaranarayanan901]

Wonderful lecture. I completed this lecture on 03-12-2022.

[@nagasanthisrinivasan4942]

sir transistor on and off condition a mathi board la eluthi irukinga sir but sollum pothu crt a sollluringa sir
ur vido is informative sir

[@ravivarma306]

ON OFF maathi eluthitinga sir... 4:45 time la

[@kalaiialak775]

ss..naanum kavanichen

[@learnwithme3517]

4.43 la ON and OFF mathi yeluthitinga sir

[@suryavasanth6893]

S , you are right bro.... Thanks

[@ravivarma306]

Ss bro.....

[@viknesvaranravinthiran4189]

sir vere level eh. TQ

[@jackshanmarsh3758]

I know the circuit diagram sir & I done it ...😊😊

[@JananiSivaShankar]

nice explanation sir

[@makeshkumar2272]

Thank you a lot sir....very interesting

[@TNROWDY-pz4xw]

Important question and tuff questions

[@smohanraj6968]

Thank you sir 🥰

[@HemanthKumar-vg9nx]

How can be fransistor off state
In that it is switch on close

[@phy25priyadharshini.n57]

Thank u sir

[@shankarshankar1787]

Any chance to take class for rewinding sir plz reply

[@poornishasenthilkumar7085]

Sir, plz provide Waveforms of base and collector of T1 & T2

[@hariharan-yi8tf]

Sir, Guess C2 polarity wrong bcoz T1 is NPN , clarity needed in this alone.

[@radhap3085]

sir..ON and OFF state maaththi pottinga.....

[@ragaviganeshan8887]

Sir You were written on off state wrongly

[@britishempiree7831]

What is the frequency of this output

[@dhinagarm2470]

👏

[@queen_trend]

Which is theirs working college sir.....

[@sushmithakarthikeyansushmi8817]

Why it's a square wave output sir?

[@TNROWDY-pz4xw]

Questions answer anuppuvingala

[@dominicnobel8709]

Ungaluku app iruka sir

[@kamleshchavan7451]

Sir there is no video in English

[@hariharan-yi8tf]

How can vce =vcc in conventional Transistor on state? Guess u wrote opposite.

[@sathyakrishna5686]

Ithink so

[@m.k.barathdass]

Yes I too have the same doubt

[@PAPPUKUMAR-xp9yo]

Sir try to explain in English .
Because someone is from North Indian

[@pappak6537]

Go and search for hindi videos

[@dr.science9609]

No we want sir to explain in Tamil
Because north Indian staff never taught us on English they only use Hindi
