QPages 419-421: Q33.1: HC Verma: Concepts of Physics - Volume 2 Semiconductors and Semiconductor Devices Pages 419-421: Q33.1 Solution: Let . Evaluate X for A = 1, B = 0, C = 1.
⚠️ Common Exam Traps & Conceptual Pitfalls
Students often forget that the bar denotes logical NOT, so they substitute the original variable value instead of its complement. Always replace $ar{A}$ with $0$ when $A=1$, $ar{B}$ with $1$ when $B=0$, etc., before performing the AND (product) operations in each term.
Let . Evaluate X for A = 1, B = 0, C = 1.
Step-by-Step Verified Solution
**Answer:** X = 1.
**Step-by-Step Explanation:**
Given: X = _BC + __CA + __AB. A = 1, B = 0, C = 1.
_ = 0, __ = 1, __ = 0.
X = 0_0_1 + 1_1_1 + 0_1_0 = 0 + 1 + 0 = 1 .
