Re: Bharat Electronics Limited placement papers and pattern

As you want to get thev details of Bharat Electronics Limited placement papers and pattern so here it is for you;

There is a written test of 2.5 hours.
The test consists of 30 questions based on aptitude.
Apart from this there is a passage consisting of 3 questions.
The questions are from:

Data Interpretation
Logical reasoning
General knowledge

The math questions are generally asked from topics like compound interest and height and distance.
These questions can be really tricky.

Placement papers of last year:
Part I—Objective questions (40 with 1.5 marks each) with 50% -ve marking.
1. Numerical problem based on modulation index fc, fm………. (formula based direct queston).
2. Poles & zeroes are at .01,1,20,100…… find phase margin/angle at f=50Hz. ans -90(By drawing bode
plot)
3. In n-type enhancement mode MOSFET drain current———– options are- increase/decrease with
inc/dec in drain/gate voltage. ans(d)
4. Gain of an directional antenna 6db P=1mw find transmitted power………(use Ptr= G * P.)
5. Multiplication of two nos 10101010 & 10010011 in 2’s complement form..
6. A ckt is given suppplied with 15v with a series of resistance of 1k and a parallel combination of 12V
zener diode and 2k resistance. FInd current through 2k resistance.
Ans: 6mA
7.A MP has 16 line data bus & 12 line addr bus find memory range……….Ans..4K(4*1024bytes)
8.Divide by 12 counter require minimum ….. no of flip flops Ans. 4
