2011 ONGC Placement Paper:
1. Modulation index increased from 0 to 1 . Transmitted power now ?
2. Deemphasis is used because
3. In FM, maximum deviation at what point of modulating signal
4. Voltage gain of emitter follower : <=1 , =1 , >=1 , cannot say
5. CRO uses which method of focussing
6. Slew Rate unit
7. Positive Feedback is same as : degeneration , regeneration
8. Integrator is : LPF , HPF
9. Lowest Efficiency in Power amplifier : A , B , AB , C
10. When PLL is used as frequency multiplier, O/P is taken from
