Morphology

sampling = sample (transparent) = sample + ing

Standard verb + -ing nominalization; the sense 'process of measuring' is a direct derivation from the verb 'sample'.

Etymology

Sampling comes from the word sample, which comes from Latin exemplum meaning 'example' or 'small part'. In signal processing, sampling is like taking regular 'snapshots' of a continuous sound wave so the wave can be turned into digital form.
