Answer: Inverted (complement) of input.
- A Identical to the input signal with no change
- B Inverted (complement) of input
- C The logical AND of two separate input signals
- D The logical OR of two separate input signals
Correct answer: B. Inverted (complement) of input
Explanation: NOT gate is an inverter: output = complement of input. If input is 1, output is 0 and vice versa.
Conductors have overlapping bands, semiconductors have a small energy gap that can be bridged by heat or doping, and insulators have a large gap that blocks conduction.
