Morphology

quantizer = quantize (transparent) = quantize + er

Regular agentive derivation from the verb 'quantize' (verb + -er) yields 'one that quantizes'; the relationship is straightforward for learners who know the verb.

Etymology

The word quantizer comes from the root quant meaning 'how much', the same root as quantity, and the ending -ize means 'make' while -er names 'something that does this'. So a quantizer is a tool that turns a smooth signal into fixed 'amounts' or 'levels', which explains its use in digital sound and images.
