What type of logic gate produces a true output only when all inputs are true?

The type of logic gate that produces a true output only when all inputs are true is the AND gate. An AND gate requires all of its input signals to be at a high level (true) in order to generate a high output (true). This means that if any of the inputs to the AND gate is low (false), the output will also be low (false).

In contrast, an OR gate produces a true output if at least one of its inputs is true. A NOT gate, also known as an inverter, simply flips the input; it produces a true output only when the input is false. The XOR gate (exclusive OR) outputs true only when an odd number of its inputs are true, meaning it can output true with only one true input but not necessarily all inputs.

Understanding the specific behavior of these gates reinforces how logical operations function in digital circuit designs, especially in scenarios where multiple conditions must be met for a process to execute successfully.
