A NOT logic gate takes a single input and produces the opposite output. The truth table for a NOT gate is as follows:

  • If the input is 0, the output is 1.
  • If the input is 1, the output is 0.

Based on the options provided, the only rows that could represent a NOT logic table must follow this pattern. Since a NOT gate has only one input, let's evaluate:

  1. first input: 0, second input: 0, output: 0 (Invalid for NOT because input 0 should produce an output of 1)
  2. first input: 0, second input: 0, output: 0 (Invalid for NOT)
  3. first input: 0, second input: 1, output: 0 (Invalid for NOT)
  4. first input: 0, second input: 1, output: 0 (Invalid for NOT)
  5. input: 0, output: 0 (Invalid for NOT)
  6. input: 0, output: 0 (Invalid for NOT)
  7. input: 1, output: 0 (Valid: for an input of 1, the output is 0 – this is not a complete representation because input 0 is missing)
  8. input: 1, output: 0 (Valid: for an input of 1, the output is 0 – same as above)

None of the responses correctly show a NOT logic table, as they all fail to provide the correct behavior of the NOT gate. The only outputs consistent with NOT logic would look like this:

  • input: 0, output: 1
  • input: 1, output: 0

If you have a specific option in mind, please clarify!
