Signal-to-noise Ratio Hard
Higher SNR implies received signal quality is:
Select the correct option:
Solution
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.
