EX-OR Question 1:
The most suitable gate for comparing two bit is:-
Answer (Detailed Solution Below)
EX-OR Question 1 Detailed Solution
- One of the most commonly used applications of the X-OR gate is, as a basic logic comparator that produces a logic ‘1’ output when its two input bits are not equal.
- XOR gate (sometimes EOR or EX-OR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd.
- An XOR gate implements an exclusive or; that is, a true output results if one and only one of the inputs to the gate is true.
- If both inputs are false (0 or LOW) or both are true (1 or HIGH), a false output results.
- XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false.
Two input Ex-OR gate:
EX-OR Question 2:
The figure shows MOS implementation of logic. The output P and Q are
Answer (Detailed Solution Below)
P = A(EXOR) B
Q = A(EXNOR)BEX-OR Question 2 Detailed Solution
From the above figure
P = A(EXOR) B
Q = A(EXNOR)B
Note:
This logic style is called “Complementary Passgate Logic” or CPL
This logic produce the outputs in true form and also in complementary form.
EX-OR Question 3:
Assuming that only x and y logic Inputs are available and their complements X̅ and Y̅ are not available, then what is the minimum number of two-Inputs nand gate require to implement X ⊕ Y ? __________
Answer (Detailed Solution Below) 4
EX-OR Question 3 Detailed Solution
A XOR gate cane be implemented with 4 NAND gates as shown in below figure.
EX-OR Question 4:
The above circuit can be used as clock generator if
Answer (Detailed Solution Below)
EX-OR Question 4 Detailed Solution
XOR gate with one input terminal HIGH acts as an inverter. Thus if
EX-OR Question 5:
The Boolean expression F(A,B,C) = Σ (1,2,3,4,6,7) can be realized by using
Answer (Detailed Solution Below)
OR, XOR
EX-OR Question 5 Detailed Solution
Given F(A,B,C) = Σ (1, 2, 3, 4, 6, 7)
One XOR gate and one OR gate
EX-OR Question 6:
Which of the following statement are correct
P) For odd number of inputs the outputs of X-OR gate is equal to X – NOR gate
Q) For even number of inputs the outputs of X – OR and X – NOR are complement to each other
R) The output of X-OR gate is always 1 when there is odd no of 1’s in input
S) The output of X-NOR gate is always 1 when there is even no of 0’s in the input
Answer (Detailed Solution Below)
All are correct
