HC Verma Chapter 45 Problem 21

Problem Statement

XOR gate inputs A=1, B=1. Find output.

Key Concepts

XOR gate

Relevant Formulas

Y = A XOR B

Step-by-Step Solution

XOR gives 1 when inputs differ. A=B=1: same -> Y = 0.

Final Answer

Y = 0

Tips and Tricks

XOR detects inequality; output 0 when inputs equal.

Common Mistakes

Always use SI units. Check energy conservation accounts for all forms.
