Superbly explained. Love the blackboard style drawing tool also !!1

Ab is the best of all to forget all the other shit completely

Greetings from Algerian dezert

Thank you, needed the refresher.

very well explained. I just need more explanation on how does the diode bias works.

Very well explained. Thank you so much for the tutorial...

What reference are you using when you say .7v at the base?

Thank you

Hello could you tell me what software you use for your pen. I like your penmanship

I love this explaination

Thank you.Very good explanation.

how can calculate the efficiency ?

What is the minimum value of the DC biasing current in class A output stage?Explain you answer

24:40 as it current flows through RL the assumption about zero volts made on 23:00 can't be true. It's should be current times RL. What did i miss?

How do you explain that the class B amplifier does not conduct when Vi=0? Shouldn't the Vcc power the transistor with a Ib, like it happens with the class A? You mentioned that all the current goes through R1 and R2... but why?

Is class A amplifier and class A push pull same thing?

pls tell the method of selecting and calculating the values of resistor ..

excellent, well explained , so clear

Can i know, what happen to class a and class b if i keep on increasing the dc/ac voltage?

I am like number 888 😊😊😊

worst video

This video is helpful. how can you help in the case where i repaired class AB amplifier, during testing process the amp blows output transistor once input signal is increased. Besides that, what should i measure to ensure that a biasing circuit output voltage and current are optimum for a pre-amp transistors. Thank you

How the positive input voltage forward bias transistor 1 having reversed bias of the upper diode ?

Really awesome lecture.

for the Class AB amp. what is a typical DC current that this driver can produce? How much current needed to drive 8ohm speaker?

Thank you so much sir, it's good explanation and thank to showing us current flow, thank you so much sir

Great video, thanks very much

Thanx

Extremely helpful!! Thank you so much

Really artistic writing

I think the class B amplifier won't have the two resistors (R1,2) AS they would result in current irrespective of the input signal.

Brilliant !

Hello M. Jellouli. This is the clearest and most engaging video on the subject that I have seen. Thank you so much. I am sure your students enjoy your lectures greatly. Regards.

Thanks for the video, Need to put something in mind and make it clear for all is that. The efficiency of Class A is 25% and Class B is 78.5%. there is huge gap between 78.5 and 50%...

great lecture sir

This helped a lot ! Thank you !

So why in case of Class A the transistor conducts for both cycles even though negative cycle cannot turn the transistor ON?

This is amazing, what a performance 😍🙏🙏 from india

awesome video!!

tnx

I know it is just an abstract, but why if the max efficiency is 30% would you show Ic going to zero on a Ic/Vce curve @4:30? I learned this before but in pieces.

Didn't knew Morgan Freeman has a Electronics degree

Thnq🙏🙏

The efficiecy of class A is 20% less than that of class B 50% so B is better than A despite the distortion???

WTF, u have a very good hand writing in letter V

WHY we need the resistor r1 and r2?????and why the transistor will not on as we have Vs onnected ,,it can take voltage from there!!why ont it be on "on" state??

You explained so clearly , thank you so much , nice tutorial sir.

sir class AB amplifier's efficiency is 50 to 78.5%

Awsome explanation
