What is 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. It can also be used to generate the gate pulse of the finite duration.
In this video, the Bistable Multivibrator is designed using the BJT and its working is explained in detail.

👌🏻👌🏻👍🏻

💚💚

[@deepika7863]

It's very helpful now
Thnk you so much sir 🙂

[@emreipek4485]

Many thanks for the video :)

[@PandeyAaditya08]

Your explanation is very nice 👍🏻

[@vinaykumarkv5830]

Well explained thank u

[@VAISHNADEVIGECEUG-]

THANK YOU SIR

[@maianh5568]

very good explaination nice one thank you

[@shivannarasareddy1931]

So nice explained

[@fahimhasan6832]

Great one

[@chamithdilshan3547]

Thank you

[@priyajitmondal6661]

Thank you so much sir ❤🙏👍🤗

[@szusszanas]

One of the best explanations so far. Helps a lot. Thank you!

[@circuitsanalytica4348]

Yes friend, he explained it nicely... if the base of transistors are pulled down the transition time of the circuit can be further reduced....

[@asifalim2540]

thanks sir...

[@AeroCraftAviation]

Great explanation! This is so simple to understand now! Thank you!

[@circuitsanalytica4348]

Yeah really nice explanation.....

[@MJ-vt1kp]

Perfect said. Your explanation is better than most of the professors that I know. Keep up the good work! :)

[@circuitsanalytica4348]

Yes really nice explanation, the time to change multivibrator states can be reduced by pulling down base of the transistors....

[@matejmarkovic6147]

why do we have to apply negative trigger pulse to the base, can it be positive pulse

[@kajalmahendru6607]

I just love ur videos...the way uh explain things is so simple...Thank you so much 😊

[@circuitsanalytica4348]

Really, he had explained this circuit nicely...

[@mayurshah9131]

Really well explained

[@mayurshah9131]

Excellent 👌👌

[@circuitsanalytica4348]

Yes he had explained this circuit really well...

[@ShaikhNazmusSadatSourav]

in my book i see a capacitor parallel with a resistor for entering set reset pulse.. why is it there?

[@farhanupaul]

Another awesome explanation. Can we use two of the outputs to drive two different loads(for Astable and bistable multivibrators)?

[@circuitsanalytica4348]

Yes you can use both outputs to drive different loads, if necessary use an emitter follower

[@sachinchaudhary-ec6nm]

Seriously u nailed it man

[@circuitsanalytica4348]

Yes Sachin, really nice explanation....

[@VAISHNADEVIGECEUG-]

WHY SIR CAPACITOR IS NOT USING IN THIS MULTIVIBRATOR SIR

[@carzycults6119]

Super sir

[@circuitsanalytica4348]

Yes really excellent, by pulling down the base of transistors, the transition time can be further reduced.....

[@metalifek1292]

4:16 that's reset not set. Right??

[@abhishankpaul]

So basically, these circuits work due to the imperfection and mismatch in the parameters of the circuit components. Is this what you wanted to say?

[@ChallaAakash]

What is difference bw self bias and fixed bias

[@circuitsanalytica4348]

In self bias the stability is better compared to other bising circuits

[@EEE-iw3fk]

Should be positive pulse. Set should be Reset.

[@VAISHNADEVIGECEUG-]

THEN WHY SIR CROSS COUPLED SIR

[@sanatghosh9278]

Sir, Is there any possibilities by which we can avoid "contact bounce circuit"problem? It is worth attending.

[@letsgettuned7811]

Other than this I understood all in this lecture

[@circuitsanalytica4348]

You can refer my videos, I had explained this circuit in detail....

[@HA7DN]

Your diagram is confusing. You should really have separated the set / reset trigger pulses, now it seems more like it's a T-ff, not an SR. Your explanation is understandable, albeit sometimes confusing. I still have no idea what do you mean by "the gate pulse of the finite duration".
Also, for anyone might be searching for "switching multivibrator" as I did, that's the same concept, but uses two diodes to direct the trigger pulse to the base of the transistor currently active, thus making it act like a T-ff.

[@letsgettuned7811]

I have a doubt that when we power up the circuit i.e., Vcc gets equally supplied at both side of transistor but it is told that Q1 transistor is having more voltage than Q2 why and how

[@circuitsanalytica4348]

That depends on the value of beta, here it is assumed that Q1 is having more beta value than Q2....

[@teluguengineering5768]

@@circuitsanalytica4348 literally trying to get attention like anything😂. !! Anyway nice to help others. Hope you may get success in youtube.

[@akhilpalelly3407]

I need derivation for this one...?

[@Gamerdu45]

mor

[@circuitsanalytica4348]

The time to change the state can be reduced by using a negative voltage source to pull down the base of transistors....
