H31-341_V2.5 · Question #756
The lower the noise figure creep value of the amplifier, the less noise the amplifier introduces.
The correct answer is A. True. Option A is correct because noise figure (NF) is a measure of signal-to-noise ratio degradation caused by an amplifier - a lower value means the amplifier adds less noise to the signal passing through it. An ideal, noiseless amplifier would have a noise figure of 0 dB, so…

Explanation
Option A is correct because noise figure (NF) is a measure of signal-to-noise ratio degradation caused by an amplifier - a lower value means the amplifier adds less noise to the signal passing through it. An ideal, noiseless amplifier would have a noise figure of 0 dB, so values closer to zero indicate better performance. Option B is wrong because it contradicts this well-established relationship: claiming the statement is false would imply a lower noise figure somehow means more noise, which inverts the definition entirely.
Memory tip: Think of noise figure like a golf score - lower is better. Just as a lower golf score means fewer strokes (less penalty), a lower noise figure means fewer noise additions to your signal.
