Questions & Step-by-Step Solutions

Which logic gate outputs true only when both inputs are false?
Correct Answer: NOR gate
  • Step 1: Understand what a logic gate is. A logic gate is a device that takes one or more inputs and produces an output based on a certain rule.
  • Step 2: Learn about the NOR gate. The NOR gate is a type of logic gate.
  • Step 3: Know the rule for the NOR gate. The NOR gate outputs true (or 1) only when both of its inputs are false (or 0).
  • Step 4: Remember that if either input is true (or 1), the output will be false (or 0).
  • Step 5: Conclude that the answer to the question is the NOR gate.
