BEFORE GIVING ANY PSU INTERVIEW I SEARCHED A LOT FOR THE QUESTIONS ASKED BUT I ALWAYS GOT INSUFFICIENT QUESTIONS. SO THIS IS MY ATTEMPT TO BRING YOU PERSONALLY EXPERIENCED QUESTIONS. I ALWAYS UPDATE IT BY GATHERING INFORMATION FROM FRIENDS TOO.

SO DO COMMENT AND FOLLOW ME FOR MORE EXPERIENCES AND VARIOUS INFORMATION.

BARC SCIENTIST INTERVIEW

Wednesday, January 2, 2019

⏩BARC (Bhabha Atomic Research Center)

Interview Date:26th June 2009.

OCES Interview.


Observe the level of BARC interview questions. Let's hear in the words of the candidate.

"I was the first candidate that day, first of all, I wished good morning to the panel. On return the main person wished me. Then he asked me where I was studying and how waw the accommodation facilities. Actually, they were trying to make me relax.

Then he asked me "tell your 5 fav subjects... I told


1. Linear Integrated ckt.
2.Control system.
3. Signal and system.
4. Digital Electronics.

Interrupted in between they didn't allow me to tell 5th subject and started questioning.

LIC.

1)Draw inverting amplifier of gain 100.
2)Draw noninverting amplifier of gain 100.
3)Draw differential amplifier of gain 100.
4) Suppose CMRR of the above differential amplifier is 100db then find common mode gain.
5)Find the exact output of the differential amplifier.
6)Common mode voltage of the differential amplifier.
7) Consider a 10v dc connected in between inverting and noninverting terminal. And 2.5v dc connected between noninverting and ground. Now asked to calculate output vtg, common mode vtg, and difference mode vtg.
8) What is the input impedance of the inverting amplifier.....
And continued...


Digital.

1) Draw an arrangement to indicate the selected pin index and the output state of MUX.
2) Generate a clock signal for a watch(i.e. of 1Hz).
3) Generate a 120v 60 Hz clock signal.
It can be generated d using high tension transformer and related ckt .but didn't know.
4) How a stable clock can be generated.
Ans is using crystal oscillator.
5) The frequency of oscillation of crystal oscillator.

6) What is the practical significance of Q factor?
7) Draw graph of Q factor of series R-L-C ckt.
8) What is really mean by an increase in and decrease in Q factor in ckt?


Signals And System.

1) we have got three identical bandlimited signals with us ...we are required to send them one after other allowing a specific delay between each of them. Also, we have to code these signals before transmitting.
2) What all ckts should be used before an ADC.
and so on up to 1:45hours...." I was interviewed.

I want the ask the student that how many of these questions were you able to answer cuz I am unable to answer like most of the questions of interview here.I think I have my concepts brushed up these things I do not study for gate this is something else.Where should I study these from.

Not only you but anybody can't answer some questions thats why they ask such questions to check your approach towards the answer. Don't worry they will politely help you to get the answer.
In previous interview I have provided a link of youtube video check it.a talk with shubham dabir.
