Here are the technical questions for electronics and communication engineering students, eie, ee, ece for the texas instruments technical test paper.
Flipflops are connected so that after 0 to 5 count occured next number is zero. So what is the counter?
Ans: mod 6 counter
simplication of some boolean expression which is simple. Boolean Expression is A+A’B.
Ans:A+B
Given inorder sequence and preorder sequence and asked to find out postorder sequence.
Some question on value of a static variable.
Given an interger in binary form,find the number of ones in that number without counting each bit.(This questin is not multiple choice question. This question carries more marks. So please take care for this question.)
1-way set associative memory is called—–
a)direct b)something c)1-way set associative 4)something
Ans: c
Fastest IPC mechanism is
a)shared memory b)pipes c)named pipes d)semaphores
Ans:c
Some page references are given. You are asked to implement it with Least Frequently Used algorithm.
Some diagram is given. Iam describinmg the diagram. A 2*1 MUX is given. The inputs are A,B. Output is C. C and A are tied together. What is the diagram.?
Ans:Latch.
Some circuit is given. Iam describing the circuit.A resistor R & a capacitor C are connected in parallel.
To this circuit another circuit which is having a capacitorof capacity 2C & an impedence Z, is connected in series.
You are asked to find out the value of Z? Note that 2C & Zare connected in series.
a)Z=2C
b)Z=2L
c)Z=L/2
d)Z=2R
Some circuit which consist of only resistors R is given. This is a repetative circuit. U have to find the effctive
resistance of the entire circuit.
A)Rin=R
B)Rin=(5+sqrt(3))/7
C)Rin=(19+sqrt(3))/8
D)None.
Two wave forms are given. You are asked to write the cirsuit to get B(second wave form) from A(first wave form).
#define SUM(a,b) a+b
main()
{
a=2;
b=3;
x=SUM(a,b)*2;
printf(“x=%d\n”,x);
}
Ans:8.
number(int i)
{
number++;
printf(“%d\n”,number);
}
main()
{
static int i=0;
number(i);
}
Ans: I don’t know.
Some circuit is given. I can’t describe the circuit. There are
3 resistors,3 capacitors & one inverter.. The question is
What is the value of the frequency such that the circuit oscillates.
A)f=RC
B)f=sqrt(3)/(Pi*R*C)
C)f=1/(Pi*R*C)
D)something
Ans:I don’t know the answer.
Question on flipflop. So gothrough all flipflops.
There are 5 questions on Nmos & Pmos circuits.
