Question 4
|
The Circuit is equivalent to:
|
Ex-OR
|
|
|
NAND gate
|
|
|
OR gate
|
|
|
AND gate
|
Question 4 Explanation:
Given circuit diagram consists of NOR gates.
NOR of “A” is A’
NOR of “A” is B’
We can see that (A’ + B’)’ is same as (A.B) , where + represents OR, represents AND and ‘ represents complement operation. This is a De Morgan’s law.
((A’+B’)’)’=(AB)’
Where (AB)’ is the NAND of AB
NOR of “A” is A’
NOR of “A” is B’
We can see that (A’ + B’)’ is same as (A.B) , where + represents OR, represents AND and ‘ represents complement operation. This is a De Morgan’s law.
((A’+B’)’)’=(AB)’
Where (AB)’ is the NAND of AB
Correct Answer: B
