Question

A gate in which all the inputs must be low to get a high output is called(a) A NAND gate(b) An inverter(c) A NOR gate(d) An AND gate

Answer 1

A gate in which all the inputs must be low to get a high output is called a nor gate.
Ans is c


Please mark as brain list please please please

Answer 2

Answer:

According to the question, the answer is option "a) A NAND gate". The reason for this answer is because, when there are input signals all low, then the output of AND gate shall be high, and a NAND gate is nothing but the opposite of the AND gate, which leads to the output as high.

Explanation:

In an AND gate all the input given should be high, in order to get an high output. When the signals are passed through a inverter, it simply changes the high to low and vice versa.
