Combinational Logic Analysis - Technical MCQs

Q1:

Implementing the expression AB + CDE using NAND logic, we get:

A (A)

B (B)

C (C)

D (D)

ANS:A - (A)

First of all, "read" the question. They asks using NAND gate. So option c having OR gate is canceled out, option D having AND gate also cancel out, now there are A and B. We are to find first AB we see option A has AB. So, accurately answer is A.
