best video of electronics seen till date
madam i really appreciate your efforts,i am also a tutor....i want some guidance from you...if u can
Best session ever thank you
Q22 answer voltage control voltage source
Is This topic suitable for instrumentation engineering?
Q34 answer on examveda showing CMRR which one is correct answer must be CMRR
Already I have mentioned in description of video
A 741 type OPAMP has a gain bandwidth product of 1 MHz. A non-inverting amplifier using this OPAMP and having a voltage gain of 20 dB will exhibit a -20 dB bandwidth of 1. 50 kHz 2. 100 kHz 3. (1000/17) kHz 4. (1000/7.07) kHz
So much useful vedio🙏🙏🙏
Very useful video.....
Thank you 😊
Thank you mam..🙏
For question no 34 the ans will be CMMR...differential amplifier is used to minimize noise
Ok I will check
Thank you ma'am 👍😊
One correction quest 22 ans c
Opamp is vcvs
Because input terminal impedance is infinite
Ma'am 28 ka i think 🤔 option (B) is the right answer
Ok I will recheck
Thanks mam
Most welcome
Please check question no 28 again..
Q28 right option is B
I think 28 ans is b
Acommon mode=A1+A2
Adifferntial mode=( A1-A2)/2
Then how common mode gain less than differential mode gain?
Mam.., Qn. 17. Overall input voltage is difference of two inputs na.
Yes
34- CMRR
Ok I will check and thanku for watching
Question No 22,,,...wrong Answer
Yes dear agree and I have already mentioned it in description
Please check
And thank you for watching
Can you please check the answer of question no 28?
Ok I will check
15:59 i think C is right!
Can u tell.me question no I will check it
I think threshold value ?
B is correct for upper threshold +vsat and lower -vsat
@@TechnoTutorials2783 38
Just I missed to write + sign for Vut =+14.63 and VLt=-14.63
Opamp is vcvs
Yes thanku for right answer
No thanks mam 😊
@@vikashprajapati6273 why it was my mistake and u correct it
Ok welcome mam
@@vikashprajapati6273 stay connected for next sem also I will complete playlist of microprocessors
Ma'am you have uploaded wrong pdf... Pls upload correct one... Thank you
Ok.i Will check
Q. 18 Should be of ans. D
Ok I Will check
Kindly teach correct things ma'am. I had solely followed your source. Now I'm cross-checking everything.
Can u tell me which question is wrong I will also check
There is one correction which I have already mentioned in description
for question 22 ans is option c
ideal opamp is voltage controlled voltage source
Que. 22 op amp is a voltage controlled current source, also it can modified to every possible option..
Ok
I have already mentioned this in description
So many wrong answers.. why misguide people
Ok , can u tell me.right answers with question numbers so that I can cross check
