What kind of logic is shown?

Explanation:
The essential idea is to identify a NAND gate as the negation of an AND operation. A NAND outputs true in every case except when all inputs are true. In other words, it behaves like an AND gate with the output inverted. For two inputs A and B, the output of a NAND gate is: - A = 0, B = 0 → output is 1 - A = 0, B = 1 → output is 1 - A = 1, B = 0 → output is 1 - A = 1, B = 1 → output is 0 If the diagram or signal pattern you’re shown matches that behavior, that’s NAND. A gate drawn like an AND shape but with a small bubble on the output indicates this inversion, which is the visual cue for NAND. In contrast, an AND gate would give 1 only when both inputs are 1; an OR gate would give 1 if any input is 1; a NOR gate would give 1 only when both inputs are 0. The observed pattern and symbol together point to NAND.

For two inputs A and B, the output of a NAND gate is:

  • A = 0, B = 0 → output is 1

  • A = 0, B = 1 → output is 1

  • A = 1, B = 0 → output is 1

  • A = 1, B = 1 → output is 0

If the diagram or signal pattern you’re shown matches that behavior, that’s NAND. A gate drawn like an AND shape but with a small bubble on the output indicates this inversion, which is the visual cue for NAND.
