If inputs A = 1, B = 0 and output X = 1, then it corresponds to the operation of a:
Correct answer: C. NAND Gate
- A. AND Gate
- B. XNOR Gate
- C. NAND Gate
- D. NOR Gate
Explanation
Explanation:If inputs A = 1, B = 0, and output X = 1, the it corresponds to the operation of a NAND Gate. An AND Gate produces an output of 1 only when both inputs are 1, which is not case here. An XNOR Gate produces an output of 1 only when both inputs are the same, which is not the case here. A NOR Gate produces an output of 0 only when both inputs are 1, which is not the case here.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
