What is the ideal outcome when improving the signal-to-noise ratio through averaging?

The ideal outcome when improving the signal-to-noise ratio through averaging specifically relates to increasing the ratio itself. Averaging multiple measurements or signals helps to reinforce the consistent signals while reducing the variability introduced by noise.

When averaging is applied, the random noise—since it tends to be less consistent across samples—will average out to a lower level, while the actual signal (which remains consistent across repetitions) will be strengthened, effectively increasing the signal-to-noise ratio. This results in a clearer picture of the underlying signal, as the relative representation of noise diminishes in comparison to the signal.

While enhancing clarity of the signal and reducing noise are important outcomes of improving the signal-to-noise ratio, the direct and primary goal of averaging is to increase the ratio itself. The other options can be considered as beneficial results, but they stem from the main objective of achieving a higher signal-to-noise ratio through the process of averaging.
