Physics and instrumentation idea
Scientific measurements often contain noise from detectors, electronics, sky background, photon statistics, or environmental fluctuations. A useful signal may be hidden beneath this noise. Signal-to-noise ratio helps quantify how clearly the signal can be detected.
SNR = signal strength / noise strength
