There were three sections:

1. Software
2. Hardware
3. Analytical

Only one MCQ question; all others to be solved analytically. Here
are some of the questions which I remember.

1. Each of the letters below represents a non-zero and unique digit.
Find the digit.
one
one
one
+one
-----
ten
Find the digits.

Ans( one = 182 , ten=728).

2. Calculate the maximum permissible propagation delay of each FF in a
modulo 1023 counter.

3. Find the error if any -

{
struct *sPtr, *nPtr
for(;*nPtr;nPtr=nPtr->next)
free(nPtr);
}

4. Find the output -
main()
{ void f(int, int);
int i, j;
i=10;
j=10;
f(++i,j++);
}

void f(int i, int j)
{if(i>50)return;
else
i+=j;
f(i,j);
printf("%d",i);
}

Ans 413121 (I think so)

5. Implement the following usin 4X1 MUX.
A'BC + AB'C +ABC'

6. How will you convert an S-R FF into J-K FF ?
