What type of logic does a NAND gate implement?

A NAND gate implements the inverse of AND logic, meaning it outputs a logic 1 unless both of its inputs are logic 1. When both inputs are true (1), the NAND gate produces a false output (0). In all other input combinations—where one or both inputs are false—the output will be true (1). This functionality can be represented mathematically: if the AND operation is denoted as A·B, then the NAND operation can be represented as ¬(A·B), where ¬ denotes negation. Therefore, the NAND gate effectively negates the result of an AND gate, reinforcing the concept of the inverse operation it performs.
