CUET PG 2021 — Computer PYQ

CUET PG | Computer | 2021

The output of an AND gate with three inputs A, B and C is HIGH when

Choose the correct answer:

Explanation

Solution

AND gate ka output HIGH tabhi hota hai jab $A = 1$ , $B = 1$ , aur $C = 1$ ho. Yaani, jab teeno inputs ek saath HIGH hote hain.

Explanation

AND gate logical multiplication (conjunction) par kaam karta hai. 3-input AND gate ke liye Boolean equation niche di gayi hai:

Y = A \cdot B \cdot C

Yahan $Y$ output hai. Is equation ke mutabik:

Agar koi bhi ek input $0$ (LOW) hota hai, toh product $0$ ho jata hai.

$\text{If any input is } 0 \implies Y = 0$
Output $1$ (HIGH) hone ki sirf ek hi condition hai:

$Y = 1 \iff A=1, B=1, C=1$
