You're on a roll —
Here's an example for the AND and NAND gates with inputs 1 and 1:
- For an AND gate with inputs 1 and 1, the output is 1.
- For a NAND gate with inputs 1 and 1, the output is 0.
Regarding your second question:
No, a NOR gate cannot directly replace an OR gate in a circuit. This is because a NOR gate's output is the inverse of an OR gate's output. An OR gate produces a HIGH (1) output if any input is HIGH, while a NOR gate produces a LOW (0) output if any input is HIGH. To replace an OR gate using a NOR gate, you would need to add an additional NOT gate (inverter) after the NOR gate to invert its output back to that of an OR gate.
