A NAND gate will output a LOW signal in which situation?

A NAND gate is a digital logic gate that produces a LOW output only when all of its inputs are HIGH. This is a fundamental characteristic of NAND gates, which are a combination of AND and NOT operations. When all inputs present a HIGH signal (1), the output will consequently be LOW (0). In any other scenario—whether one input is LOW or all inputs are different—the NAND gate will output a HIGH signal.

Understanding this behavior is critical when using NAND gates in circuit design, as it allows for the implementation of various logical functions and conditions in digital systems. Therefore, the specific condition of all inputs being HIGH directly leads to a LOW output from the NAND gate.
