Etymology
Etymology Information

'bandlimit' is a 20th‑century technical compound coined in English from the nouns 'band' + 'limit' to name the act or value of limiting a signal's frequency band.

Historical Evolution

'bandlimit' formed by combining 'band' (Old English/Old Norse root) and 'limit' (from Latin through Old French); the modern compound arose in electronics and signal‑processing literature in the 1900s and became common as 'band-limited' and 'bandlimit' in technical texts.

Meaning Changes

Initially a literal compound meaning 'limit of a band', it came to be used specifically in signal processing to mean 'the maximum frequency or operation of limiting a signal's frequency content'; the technical sense narrowed from a general phrase to a specialized term.
