Which logic gate will output a logic "1" only if both of its inputs are also "1"?

The logic gate that outputs a logic "1" only if both of its inputs are also "1" is known as the AND gate. The functionality of the AND gate can be summarized by its truth table, which indicates that it requires both inputs to be in the high state (1) to produce a high output.

For instance, if you have an AND gate with inputs A and B, the output will only be "1" when A is "1" and B is "1". In all other cases—when either input A or input B is "0" (or both are "0")—the output will be "0".

This characteristic is fundamental in digital logic design and is widely used in various applications, such as building complex circuits and performing logical operations.

The other logic gates listed have different output behaviors. For example, a NAND gate outputs "0" only when both inputs are "1", while the OR gate outputs "1" if at least one input is "1". The XOR gate outputs "1" only when the inputs are different. Each of these gates has its own unique logic that serves different purposes in circuit design.
