can you help me i want exercices and problems to practice because i have exam

[@farhanupaul]

I can't thank you enough for your videos. You explain topics at its simplest form.

[@neilcullimore5798]

Thank you so much for your hard work. I agree with a previous contributor....the new gain with the common base amplifier added at the front end is 1486.

[@sreenivasuluyegatila]

Greatly appreciates your work brother. I didn't understand these concepts in my b.tech.

[@nilmadhabghosh3448]

The answer to the question is, gain = 1485.45 , Thanks for the video 😊

[@mnada72]

Thank you, I really appreciate the effort and quality of your content. I am keen to learn from every single video in this channel.

[@farhanupaul]

Overall voltage gain at 9.37, shouldn't be Vo2/Vin1?

[@sainikhilkanchumarthi2267]

Thank you from the bottom of my heart!!!!!

[@vishnusathvikpeddinti4914]

you are awsome plz make such videos many and more

[@poojashah6183]

Best video 👌🏻👌🏻👍🏻

[@1SmokedTurkey1]

Great explanation! Are you planning on making a video purely about impedance matching? If not, my question would be if I'm planning on amplifying the signal from a Colpitts Oscillator circuit. I'd obviously need a buffer stage otherwise the circuit would be loaded and the signal ruined. In this case would a common base buffer work (since it's a high freq signal) or a common collector buffer is more fitting?

[@GSPmediaO28]

Very nice explanation, keep it up 👍

[@_AnanyaMukherjee]

Great explanation! Can you make a video on RC Coupled Amplifier ?

[@ElectronicsCircuitHubECH]

Excellent Content

[@khoinguyen4455]

I have a question: what will be the effect of adding 2 emitter resistors (one to each stage) on the overall voltage gain equation as well as of each stage. Thank you 🙏

[@ALLABOUTELECTRONICS]

I have already covered it in the separate video. Because of the emitter resistor, the gain of the individual stage as well as overall gain will reduce. Here is the link of the video: kzbin.info/www/bejne/oXSxqIhjhKx-Y7c

[@khoinguyen4455]

ALL ABOUT ELECTRONICS Thanks 🙏

[@abhishekprajapat4346]

From CC at intial cascade, the ''' GAIN (overall) = 1485.4363 "". Pls. give confirmation feedback.

[@adi5962]

I got 1484.7

[@farhanupaul]

So CB is used for impedance matching, so we don't get any reflection voltage? Please do some videos about high speed connections. Thank you.

[@bhavanihm7122]

Excellent video....

[@yugandharkalimireddy9019]

Sir I currently studying 2nd year of engineering in EEE But I do like the electronics the most But I am not able to buy the best book for the electronics . whatever books I do purchased till now are not so easy to understand It is effecting our studies So please sir do recommend the best book to learn electronics ☺ Please sir ….............................

[@fernandohood5542]

Would be good to see this theory translated into a working amplifier.

[@chanchlakumari8513]

Tq so much sir

[@abhijithanilkumar4959]

Sir please make a video on power amplifiers Really hard to understand

[@ALLABOUTELECTRONICS]

Will make the videos on it soon.

[@abhijithanilkumar4959]

@@ALLABOUTELECTRONICS Thank you sir

[@Way2Know]

Good video

[@Harshavardhan-zr2ip]

Sir please complete multi stage amplifier quickly

[@chromicle]

In the last diagram, is there Rs as you shown the before but you didn't shown that in last diagram

[@istvanegle7442]

The answer is Av=1515
