Logic Gates
In a two input logic gate, when one input is '1' and the other is '0' (zero), the output is '1'. But even if both inputs are '0' (zero), the output is '1'. The logic gate is
Show answer and solution
Answer: (c)
- Inputs (1, 0) give 1 and inputs (0, 0) give 1.
- AND gives 0 for both; X-OR gives 0 for (0, 0); NOR gives 0 for (1, 0).
- NAND gives 1 unless both inputs are 1, so it fits both rows.
- So the answer is (c) a NAND gate.
