Morphology

sampling + rate

The meaning is directly derivable from combining 'sampling' (taking periodic measurements/samples) with 'rate' (frequency or amount per unit time): it denotes how often samples are taken. This noun–noun composition is regular and predictable (and has clear equivalents in other languages), so a B1 learner who knows both constituents should understand it.

Etymology

The noun sampling rate comes from the idea of sampling, taking many small samples, like quick snapshots of a sound, every 'second'. So a higher sampling rate means more snapshots each 'second' and a closer digital copy of the original sound.
