Morphology

signal + level

The meaning is directly compositional: 'level' denotes an amount or measured magnitude and 'signal' specifies what is being measured, so 'signal level' straightforwardly means the strength/amount of a signal. This noun–noun combination follows common cross-linguistic measurement patterns, so a B1 learner who knows both words can infer the MWE's meaning even if the term is used in technical contexts.

Etymology

Signal level comes from the simple image of a message and its height: a signal held at a higher level is easier to see or hear, so a higher level means a 'stronger' message. That's why 'signal level' today means how strong or loud an electrical or sound signal is.
