Etymology
The word 'unmodulated' is a modern English formation built upon the older verb 'modulate.' The core concept originates from the Latin verb 'modulari,' meaning "to measure, regulate, or adjust rhythmically," which itself derives from 'modulus,' a diminutive of 'modus' (measure, manner). The prefix 'un-,' a common Germanic negation, is attached directly to the past participle 'modulated' to create a straightforward adjective. Therefore, the literal construction "not adjusted" evolved specifically to describe sounds—especially in electronics, music, and speech—that lack the controlled variation in frequency or amplitude which defines a modulated signal or a expressive tone.
