Two 4 bits binary numbers, $A = 1101$ and $B = 1010$ are given in the inputs of a logic circuit shown in figure below. The output $(Y)$ will be :
Answer: (A) $Y = 1101$
Concept. $Y=\overline{\bar A\cdot B}=A+\bar B$, applied bit by bit.
Step 1. Bits. $A=1101$, $\bar B=0101$.
Step 2. OR. $1101+0101=1101$.
Answer. $Y=1101$ (Option A).
