Morphology
signal-to-noise + ratio
The meaning is directly derivable from the constituents: it denotes the ratio (numeric relation) comparing the strength of a signal to background noise, which follows straightforward compositional logic. Although technical, the construction mirrors common 'X-to-Y ratio' patterns found across languages, so a B1 learner who knows the words 'signal', 'noise' and 'ratio' can infer the meaning.
Etymology
Signal-to-noise ratio comes from an easy picture: the signal is the voice or message you want to hear and the noise is the background sound that makes hearing hard. So it measures how much 'signal' stands out from the 'noise', or how clear a message is.
