Question

In______if A=1, B=C then output Y=C. a)OR gate b)AND gate c) EX-OR gate.
​

Answer 1

Answer:

answer is OR gate

or gate =A*B=1*C=C

Y=C

Answer 2

In AND gate if A=1, B=C then output Y=C.

To understand the answer properly, we have to know more about AND gate and its functionalities.

AND gate :

• AND gate is one of the most important logic gates which has two or more inputs, but only one output.
• If, A and B are two inputs of AND gate, and if Y is the output of the said AND gate, then Y = A . B (Boolean expression of AND gate).

In the given case,

• Inputs are - 1) A = 1 ; 2) B = C
• Output is Y
• In case of AND gate we get, Y = A.B
• Now, A . B = B . A (applying commutative law)
• B . A = C . 1 (putting the given input values)
• Now, C . 1 = C (applying identity law)
• So, Output = Y = C
• Desired output has been obtained in case of AND gate. So, the correct answer will be AND gate.

So, only in the case of AND gate the output becomes Y=C
