GROUP 'B'

Answer Any Four Question 


2.Prove De-Morgan's Law Using Truth Table ?

Ans: De-Morgan's First Law : The first theorem of De Morgan's Law defines that the inverted result from AND Operation is the same as the OR operation of a complement of each variable where the Result equal NAND Operation.

De-Morgan's First Law Formula : (XY)' = X' + Y' 

De-Morgan's First Law Truth Table

XYX'Y'X•Y(X•Y)'X'+Y'
0011011
0110011
1001011
1100100
Here Prove The First De-morgan's Law Formula. 
(XY)' = X' + Y' 
L.h.s = R.h.s

De-Morgan's Second Law : The Second theorem of De Morgan's Law defines that the inverted result from OR Operation is the same as the AND operation of a complement of each variable where the Result equal NOR Operation.

De-Morgan's Second Law Formula : (X+Y)' = X'  Y' 

De-Morgan's Second Law Truth Table

XYX'Y'X+Y(X+Y)'X'•Y'
0011011
0110100
1001100
1100100

Here Prove The Second De-morgan's Law Formula.
(X+Y)' = X'  Y' 
L.h.s = R.h.s



3. Using K-Map, obtain the minimal sum of pro- duct expression of the following function:
 F(x,y,z,w)=Σ(1,3,4,5,7,9,11,12,13,15)


4. Difference between sequential and combinational circuit.
Ans : Combinational Circuit: Combinational Circuit is defined as the time independent circuit which does not depend on the previous input to generate any output is called as Combinational circuit.

Sequential Circuit: Sequential Circuit are those which are clock cycle dependent and depend On the current as well as previous input to generate any output
S.No Combinational Circuit Sequential Circuit
1. In this Output depends only on present Input In this output depends on present as well as past input.
2. Speed Is Fast Speed Is Slow
3. It is designed easy it is degisigned though as compared to Combinational Circuit
4. There is no feedback between input and output. There exists. a feedback path between input and output
5. This is Time Independent This is time Dependent
6. Elementary building blocks: Logic gates Elementary building blocks: Flip-flops



5. Simplify the Boolean Expression
    xy + x(y + z) + y(y + z).

Ans: x y + x (y + z) + y (y + z)
    =    xy + xy + xz + y (y + z)
    =    xy + x z + y ( y + z )
    =    ху + xz + yy + yz
    =    xy + xz + y + yz 
    =    xy+ xz + y
    =    xy + y + x z
    =    y + x z

6. Explain Half Adder
Ans: A half Adder is a type of adder. an electronic circuit that performs the addition of numbers. The half Adder is able to add two single binary digits and provide, the output plus a carry value. It has two input's, called A and B. and two outputs. S(sum) and C (carry). The common representation uses. a XOR logic gate and am AND logic gate.

Truth Table Of Half Adder 
INPUT INPUT OUTPUT OUTPUT
A B S(SUM) C(CARRY)
0 0 0 0
0 1 0 1
0 1 1 0
0 0 0 1



7. 8 Bit subtraction of (17)10, (-13)10 using 2'complement.
Ans: 
Here A = 00010001, B = 00001101.
Find A - B = ? using 2's complement
First find 2's complement of B = 00001101

Note : 2's complement of a number is 1 added to it's 1's complement number.
 
Step-1: 1's complement of 00001101 is obtained by subtracting each digit from 1
11111111
-00001101

11110010


Step-2: Now add 1 to the 1's complement to obtain the 2's complement :
11110010 + 1 = 11110011

Step-3: Now Add this 2's complement of B to A

111111
00010001
+11110011

100000100

Hints : (Move mouse over the steps for detail calculation highlight)


The left most bit of the result is 1, called carry and it is ignored.
So answer is 00000100
