Universal (NAND , NOR) and Exclusive Gate (Ex-OR , Ex-NOR Gate)

NAND Gate

NAND Gate ko universal gate bhi kaha jata hai. NAND Gate NOT aur AND gate ke combination se bana ek gate hota hai. NAND Gate me do ya do se zyaada input diye ja sakte hain lekin output kewal ek hi liya ja sakta hai. Agar diye gaye sare hi input 1 honge tabhi iska output 0 hoga aur sari conditions me iska output hamesha 1 hi hoga.

NAND Gate ka output AND Gate ko reverse kiye jane par paya ja sakta hai.

NOR Gate

NOR Gate bhi ek universal type ka gate hai. NOR Gate, OR Gate aur NOT Gate ke combination se bana hua gate hota hai. isme bhi NAND Gate ki tarah hi do ya do se zyada output diye ja sakte hain. NOR Gateme jab diye gaye sare hi input 0 honge sirf tab hi iska output 1 hoga baaki saari conditions me iska output 0 hi rahega.

Ex-OR Gate

Ex-OR Gate ko XOR Gate bhi kaha jata hai. Ye Gate do NOT Gate, do AND Gate aur ek OR Gate ke combination se bana hua gate hota hai. Isme kewal do hi input diye ja sakte hain aur ek unse ek output gain kiya ja sakta hai. Inka output 1 sirf tab hi hota hai jab diye gaye input unequal hote hain lekin jab inputs ki values same ho jati hain to inka output 0 ho jata hai. In Gates ka istemal Parity Checking, Binary numbers ko add karne aur Code Conversion me kiya jata hai.

Ex-OR Gate ke special output ki wajah se ise anti-coincidence gate ya inequality detector bhi kehte hain.

Ex-NOR Gate

Ise Exclusive-NOR Gate ya X-NOR Gate kehte hain. Ye digital electronics me do inputs ki equality ko compare karne ke kaam ate hain.Ex-NOR Gate,  Ex-OR Gate aur NOT Gate ke combination se banta hai. Agar Ex-OR Gate ke output ko invert kiya jae to Ex-NOR Gate ban jata hai. Ex-OR Gate ki tarah isme bhi do input dekar ek output gain kiya ja sakta hai. Is Gate me output 1 sirf tab hi hota hai jab dono input equal ho i.e. dono inputs 0 ho ya to 1 ho.
