Logic Gate Question Every JEE Student Should Solve! 🔥 | Find When Y = 0
❓ Question The output Y = 0 when: A = 1 and B = 1 A = 0 and B = 1 A = 1 and B = 0 A = 0 and B = 0 (Which logic gate does this condition represent?) 🖼️ Question Image ✍️ Short Solution To find the correct answer, we analyze when the output becomes 0 for different input combinations. Step 1 — Recall common two-input logic gates Gate Expression Output (Y) = 0 occurs when… AND Y = A·B When A = 0 or B = 0 OR Y = A + B When A = 0 and B = 0 NAND Y = ¬(A·B) When A = 1 and B = 1 NOR Y = ¬(A + B) When A = 1 or B = 1 XOR Y = A ⊕ B When A = B (both 0 or both 1) XNOR Y = ¬(A ⊕ B) When A ≠ B (0,1 or 1,0) Step 2 — Given condition The question states that Y = 0 when A = 1 and B = 1. Let’s check which gate satisfies this. For AND gate : A=1, B=1 → Y=1·1=1 → Y≠0 ❌ For OR gate : A=1, B=1 → Y=1+1=1 → Y≠0 ❌ For NAND gate : A=1, B=1 → Y=¬(1·1)=¬1=0 ✅ That’s the correct condition! Step 3 — Verify other inputs (optional cross-check) Let’s create the ...
