Physics - Semiconductors Question with Solution | TestHub

For an OR gate, when $A=0$ and $B=0$, the output is $C=0$.

For an AND gate, when $A=0$ and $B=0$, the output is $C=0$.

For a NOR gate, when $A=0$ and $B=1$, the output is $C=0$.

For a NAND gate, the output is $1$ unless both inputs are $1$. Thus, when $A=0,B=0$, the output is $C=1$ and when $A=0,B=1$, the output is $C=1$.

Therefore, the given conditions are satisfied only by a NAND gate.

Answer: NAND
