Logic Gates and Universal Gates – Rankers Physics

Logic Gates: Practice Problem & Solution

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): A digital circuit that follows logical relationship between the input and output voltages are generally known as logic gates. Reason (R): NOR and NAND gates are not considered as universal gates. In the light of above statements, choose the correct answer from the options given below.
Both (A) and (R) are true and (R) is the correct explanation of (A)
Both (A) and (R) are true but (R) is not the correct explanation of (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Logic Gates. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion is true because logic gates process signals based on logical relationships. Reason is false because NAND and NOR gates can implement any Boolean function, meaning they are universal gates.
