Solution
Correct Answer:
Better
The Signal-to-Noise Ratio (SNR) is defined as the ratio of the power of the desired signal to the power of the background noise: SNR=PnoisePsignal. A higher SNR means the desired signal is much stronger than the noise, leading to clearer reception, lower error rates, and better overall quality. In audio, this means less 'hiss'; in data, it means fewer bits are flipped.
This hard difficulty physics question is from the chapter communication systems, covering the topic of signal-to-noise ratio hard. It appeared in the 2025 exam.
