Solution:
QUESTION: 6

What values of A, B, C and D satisfy the following simultaneous boolean equation? 1. A = 1. B = 0, C = 0, D = 1
2. A = 1, B = 1, C= 0, D = 0
3. A = 1, B = 0, C = 1, D = 1
4. A = 1, B = 0, C = 0, D = 0

Solution: i.e. A must be 1 and B must be 0 From (ii) we have i.e. C is also 0.
Putting the values of A, B and C in (iii) For, the above equation to be true D is independent.

QUESTION: 7

The number of 1s in the binary representation of (3* 4096 + 15*256 + 5* 16 + 3) are

Solution:

3*4096 + 15*256 + 5*16 + 3
As we can see that Hence, they only remains as same in number of 1’s and when any other number is multiplied by themselves, the number of 1 ’s is only the count of the number of 1 ’s in other multiplicant. ∴ correct option is (c)

QUESTION: 8

Which of the following sets of components is/are sufficient to implement any arbitrary boolean function:
1. XOR gates, NOT gates
2. 2 to 1 multiplexers
3. AND gates, XOR gates
4. Three-input gates that output (A • B) + C for the inputs A . B. and C.

Solution: 2 to 1 multiplexer is a universal circuit.

QUESTION: 9

Zero has two representation in

Solution:
