My Interview was on 30 June 2009
There are 8 interviewers - out of which one is lady. All are very cool
The chairmen of committee ask me are you employed, then i said yes followed by my company project. They are not interested in projects then they ask which subjects we touch and which subjects we do not touch. So i said i have read all subjects, you can ask from all subjects including Digital electronics and Communication. So, one of them start with communication. In between one them ask, have you done diploma, i said yes sir PGDEVD DIPLOMA form CDAC where i have read embedded systems and VLSI design, i think it gives some positive impact on them.
Questions ask by them as follows:-
1. There is one transmitter and two receiver, one is 100m away and other one is 400 m away. Which Rx receive more signal and why and also determine the ratio of signal receive at receivers antennas.
2. What is modulation index for AM and FM.
3. There are two amplifiers in cascade having bandwidth bw1 and bw2 (some values in DB). What is resultant bandwidth. (GAIN = g1*g2 or GAIN in db = G1 + G2 in db)
4. Can you draw bode plot(some figure is given).
5. Why microwave is so called.
6. Why we can not use simple RLC circuit.(Because they produce Low frequency which is not in GHZ)
7. What are resonators. what is difference between oscillator and resonator. what is difference between resonator and resonance.
