# Robert-Bosch Placement Paper

ROBERT BOSCH PAPER ON 24th JUNE AT BANGALORE

Hai,
I am Naresh Gurram(SBIT). here I am submitting ROBERT BOSCH question paper. I am from EEE background. There will be separate papers for ELECTRONICS students and COMPUTER students.

Friend prepare well all the topics which the is covered since the tech paper is having all the topics Which are related to Our engineering sudents like

basic electronics , nt,control systems, eletrical machines,digital electronics, aptitude, & gen physics & gen english, c ques play key role

C & aptitude is very easy

For ‘C’ go through Seventh Kanithkar

Questions ; 60
Duration : 1 hour

This paper is for EEE,ECE,EIE &IT

SECTION 1(TECHNICAL)

8. Power gain of an amplifier having i/p gain of 20W and output gain of 20mW is

9. There was a RC circuit given with AC voltage source. Expression for capacitance was asked for charging condition. Choices were somewhat like this: a) some value multiplied by exp (-t/T)

10.SCR s are connected in series to get

11. Which one of the following is used for high speed power application?

12. One question related with SCR timing dia

13. SCR is used for

14. State in which o/p collector current of transistor remains constant in spite of increase in base current is

15. what is the resonant frequency of parrel RLC circuit of R= 4.7 komh L= 2 micro Henry and c=30pf.

16.for the parallel circuit (one figure is given) Is= 10mA. R1= 2R, R2=3R, R3= 4R. R is artritary

17 . Two ques on control sys like the sys will be stable when the roots are

20 The ques on Niquest plot

21 0ne ques on root locus

22. One more question related with ADC like voltage is 8 volts. freqency 2 Mega hz. what is the converssion rate

23. Question related with serial in parallel out shift register…What is output sequence?

24. Given one RLC circuit in which values of R, L and C were given. What is the value of frequency f?

25. #define A 10+10
main ()
{
int a;
a=A*A;
printf (“%d”, a);
}
a) 100 b) 200 c) 120 d) 400

ans : c
26. main(){
int n=0;
while(n>32767)
pf(“%d”,n);
n++
}

ans ; indefinite loop here ihe loop will continue again & again ie after 32767 the go to -32768

27. if (fun ())
{
X++;
}
X gets incremented if and only if

28. In dynamic memory

29. Short, int and long integers have how many bytes?

30. A (n) is -----------filter combination of

31. according to ohms law the current density is proportional to

32 Two more ques on gravity ie body is projected then find the time of fall and some physics ques

33. Structure comparison is done

34. The system in which communication occurs in both ways but not simultaneously in both ways is

35. main ()
{
int a=5, b=6;
int i=0;
i=a>b? a:b;
printf (“%d”, i);
}

36. int fun (char c)
{
int i;
static int y ;}

37. how would you insert pre-written code into a current program?

38.structure may contain

39 One ques from pointer declaration

Section II
40 If a>4,b<-1 then which of the following is true

41 In a class out of 150 studs participated in various games foot ball ,basket ball, cricket are 120, 130,135 respecly and 5 stud are not playing any one of then then find the least no of studs which are are playing all the games

42. 20 men can do a work in c/2 days & 30 women can do the same work in c/3 days then how many days will take to complete the work when 20 men &30wmen work together

43. find the lateral surface of a cone with diameter of base 12feet . and the latent height is 24feet

44. Ann is shorter than Jill and Jill is taller than Tom. Which of the following inferences are true?

45. Sum of squares of two numbers is 404 and sum of two numbers is 22.Then product of two Numbers?

46). (10 | 7) would produce

ENGLISH section
Remaining are English questions which contain Correction of sentence , Synonyms & one puzzle which is very lengthy
And I feel tough
BEST OF LUCK
